Kinja blog The Dogs has unearthed this funny 1993 clip from Late Night with Conan O'Brien, starring a very young Louis CK, Robert Smigel—aka Triumph the Insult Dog—and Adam Sandler.
Just when I thought my Louis CK crush couldn't get any bigger, I find this. I'M DOOMED. Although the best line comes from Robert Smigel here: "That's not how a Cocker Spaniel sounds." To quote myself circa 1993: Duh hickey!
