Who doesn't love TV show theme songs? It's honestly one of my favorite things about watching TV shows - unfortunately you don't see much of that these days on broadcast TV. But Jimmy Fallon and the cast of the new NBC show Guys With Kids performed a montage of some of the most popular TV theme songs of all time. The montage included the theme songs of shows like Friends, Full House, The Fresh Prince of Bel-Air, Saved By The Bell, and many, many others. I recognized many of the songs, how many did you recognize?
