Large Ham/Advertising

Examples of Large Hams in Advertising include:

George the Volcano, from the UK Volvic ads. "Hel-lo, Tyrannosaurus Allan! I'm filling my water with volcanicity!"
Peyton Manning can really CUT THAT HAM in his commercial appearances.
Steve Ballmer in this Windows commercial.
- He also gets really excited during presentations. Especially if they are about developers or advertisers.
