Here's a normal person problem that you totally can understand and relate to: apparently supermodel Elle Macpherson regrets appearing on Friends because she had no idea the show was so popular. Macpherson played Joey's roommate and eventual hookup Janine for a five-episode run back in 1999.

"If I’d known how important it was in the US, or how long it would be on TV, I may not have chosen to do it," Macpherson, who is Australian, told TV Week. "It was a lot of pressure if you look at it in the way that it will be around for 20 or 30 years."
