 It's Bullseye. I'm Jesse Thorne. If you always thought there were no heartwarming lessons on Seinfeld, you should try It's Always Sunny in Philadelphia. The latter show has been on the air for almost two decades. Caitlin Olsen, my guest, plays Sweet Dee Reynolds on the show. Olsen also performs on the TV comedy Hacks. She plays DJ Vance on that show, the daughter of Gene Smart's character, Deborah Vance.
