Today's TV Crossover is a little different than usual (see here and here). You may have seen Judy Greer on this week's Modern Family, where she played Jay's old high school girlfriend, Denise.
But Judy has also appeared on many of our other favorite shows, including:
It's Always Sunny in Philadelphia
"The Aluminum Monster vs Fatty McGoo"
(She voices the trampy secretary, Cheryl)
And, of course...
(She played Kitty Sanchez, secretary/girlfriend extraordinaire)
What else has Judy been in?
