Longtime readers of the site know there are a few subjects we post about more or less constantly: Kate Upton and her continuing adventures traveling the world while wearing little clothing. Bouncers, and what happens when their fists meet clubgoers' faces. And, of course, Nick Offerman, and, well, pretty much anything he does.

Offerman is a man's man, however he revealed last night that he has a softer side, which comes out through his love of musical theater. On the "Late Night with David Letterman" Wednesday, he pitched a variety show he's been working on that will consist of a "series of anecdotes, cautionary tales, with minor nudity," as well as a few songs. One number is "The Rainbow Song," which he wrote for his wife, Megan Mullally. It contains the lyrics, "Please don't deny my advances/For you are the one I want to impale." And it's absolutely hilarious.
