For no reason at all (other than the recent occasion of St. Patrick's Day maybe?), you just need to watch this hilarious bit from the late '90s with Amy Poehler guest-starring on "Late Night with Conan O'Brien" as Andy Richter's insane, Conan-loving little sister.

Poehler played versions of this character on Comedy Central's "Upright Citizens Brigade" and later on "SNL," but its raw power is most unbridled here. Remember how long sketches used to go on these shows? I miss it!
