Just how involved is Jimmy Fallon with his new comedy Guys with Kids? Apparently, the executive producer is not only very hands-on, but voice-on too. It turns out that Fallon sang the theme to the NBC sitcom!

Over the years, Fallon has released two albums and honed his pipes on Late Night, Saturday Night Live and even a 2012 Primetime Music Special, so it comes as no surprise that the funnyman showed off his skills in the show's opening credits.
