30 Rock S4E5 “The Problem Solvers”
Modern Family S5E24 “The Wedding, Part 2”
I think this is the only scene in Modern Family in which these characters are both onscreen at the same time. Until this point, I had thought that Claire/Sal were both portrayed by the same actor, and that it was a joke that the rest of the characters did not see the resemblance.
They were obviously different for me. The one is the mother of JD’s son in Scrubs, and the other is the love interest for Adam Sandler in Happy Gilmore.
