It's also kinda interesting to imagine him before the show doing sort of a Rockyesque warm up in front of the mirror.
George (to himself in mirror): "Come on old bean. Tonight's show is going to be the best EVER. YEAH!! GET PUMPED!!" *slaps self repeatedly* "You NEED this. They NEED this. YOU NEED IT!!" *looks at steroids* "NO! No baby, you don't need the milk. BABY DOESN'T NEED THE MILK!"
Random Studio Guy: "George, you're on in five."
George (to himself in mirror): "Alright Georgie, alright, deep breaths. Hummm..hummm..dead babies, Antarctica, dead babies, Antarctica, pusillanimous, pusillanimous, pusillanimous. ALRIGHT LET'S DO THIS."
Actually, thinking of George in almost any situation is kinda funny, now that I think of it.
