You probably know Rob Delaney from Catastrophe, the brilliant sitcom he created with Sharon Horgan, or from his movie roles in Bombshell, Hobbs & Shaw, and Deadpool 2. He's now showing off his slapstick skills in the new Home Alone movie, Home Sweet Home Alone, so we figured it was time to get to know him better. Here are 10 things you might not know about this consistently funny guy.
1. He auditioned to play Phil Dunphy in Modern Family, the role that ultimately went to Ty Burrell.
Delaney shared his audition experience on Twitter in 2019, writing: "I *think* it was written for him [Burrell] but [the] network made producers audition other actors anyway 'just to be safe.'"
2. He was supposed to play Elvis Presley in the Elton John biopic Rocketman.
"I did shoot a couple of scenes in the film as a guy named Elvis Presley, who you may have heard of, and they even dyed my hair black for it," Delaney revealed on a BBC 6 Music interview, according to NME. "In the make-up trailer, they said: ‘Do you want the temporary dye or the permanent?' My hair is black in another movie because of playing Elvis in Rocketman, which got cut, which is very funny, but that's just the way the ball bounces sometimes."
3. In 2012, he was voted the "funniest person on Twitter."
It was the first and only time this accolade was awarded, so in a way, he still holds the honor. You can give him a follow at @robdelaney. 
4. He accepted his role as Peter in Deadpool 2 without asking what it was.
"It so happened that Ryan Reynolds watched Catastrophe and enjoyed it," Delaney revealed on U.K. TV show Sunday Brunch, according to Digital Spy. "And so he just called and said, 'Hey, do you want to be in the movie?' And I was like, 'Yeah, I'd like that.' And he was like, 'Do you want to know what you'll be doing?' and I said, 'I don't care.'"5. He's a big fan of the NHS because of the care it gave to his son, Henry, before he sadly died of a brain tumor in 2018.
"What was amazing about having a child get very sick here [in the U.K.], and then sicker, and then disabled, and then ultimately die, is that as nightmarish as that was and still is, it didn't bankrupt us," Delaney told Esquire last year. "Nor did we have the fear while he was sick that it would, which so many Americans have. Being the vice president of a family that now has five living members, I would feel irresponsible moving my family out of a country that has true universal healthcare that's free at the point of use."
6. He revealed last year that he has undergone a vasectomy.
In a candid and very funny article for The Guardian, Delaney wrote of the procedure: "I just had to ride that pain wave, baby. I 'comforted' myself with the knowledge that what I was enduring would probably feel like a pleasant respite compared with what my wife went through four times to bring our chunky sons into the world."
7. He's a recovering alcoholic who has been sober for nearly 20 years.
Delaney posted a tweet marking his 18th year of sobriety in February 2020. "As of today I’ve been sober for 18 years," he wrote. "I hesitated posting this today but I feel duty-bound to let those who need help with booze or drugs know that there is another way. Thank you to everyone who’s helped me along the way."
8. He doesn't necessarily think his comedy is more British or more American.
"I feel comfortable making jokes here [in the U.K.] and I feel accepted as a person of humor," Delaney told The Guardian recently. "But the idea that my comedy would appeal to one populace over another makes me physically sweat. In Catastrophe, which was most watched in the U.S. and the U.K., we would always try to make sure that jokes would work in both places – unless we found one that would be such a home run in one place that we didn’t care what the other place thought."
9. In 2019, he became the first guest on U.K. kids' network CBeebies to read a bedtime story in Makaton.
Makaton, a language program incorporating signs as well as speech and symbols, is often used to aid communication among people with cognitive impairments or neurological disorders. 
"I am beyond honored to be the first person to read and sign a book using the Makaton language. Our family learned Makaton to be able to communicate with our son Henry, who couldn't speak due to a tracheostomy," Delaney told The Makaton Charity at the time. "We're sad Henry isn't here to see it but we're happy other families will get to enjoy a story told in Makaton."10. And finally, he says he's never been tempted to wax his luxuriant body hair.
"I think we have equalized a bit there – where there was a big rip-all-your-hair-off thing for a while, I think people now are like: that’s a lot of work, and the pendulum has swung back in the right direction," Delaney told The Guardian. "I never thought I should shave my body or anything like that. Never felt it, never did it."
