* BrokenBase: The man himself is divisive, but there's also some debate over whether or not he should ad lib. He's generally agreed to be a good performer when he commits to a script and character, but is very hit-or-miss when allowed to [[HarpoDoesSomethingFunny "go off"]], even though it usually makes for some of his more memorable lines.
* EnsembleDarkhorse: Many of his early roles were as "that guy who was in that thing," playing memorable side characters in ''Film/AustinPowers'' and ''Film/{{Zoolander}}''.
* HilariousInHindsight: In ''Film/JayAndSilentBobStrikeBack,'' his character was named Marshall Willenholly in honor of ''Film/LandOfTheLost''. He's later play Marshall in the show's film adaptation.
* LoveItOrHateIt: His comedy and acting style are an acquired taste. His IdiotHero and/or UnsympatheticComedyProtagonist characters are either charming or obnoxious, and there's not much wiggle room.
* MemeticMutation: Two words: Cowbell and Roxbury.
