If Jim Gaffigan comes to your town, go see him.
Jenny, Molly and I saw him last night and we laughed so hard our faces hurt.
Really. Go see him. You'll thank me.
Update: Here is a link to Jim's bit on manatees from Dr. Katz. (I think this should work. I'm having a bit of trouble with Flash right now, but you shouldn't let that stop you.)
