Best Cameo?

There are so many.

Michael Richards' rant, "Did the mention the wife?!?" "No, no, they didn't mention the wife! Are you happy? Oh yeah! Yes, yes, I'm insensitive!", Charles Grodin's response to Anthony LaPaglia considering his car and incessantly tapping on his dashboard "Does this bother you?", "No, it's one of my favourite things" (cue withering glance), or Phil Hartman as John Johnson AKA 'Vicky' speech about Machine Gun Kelly following a major eyeroll at Myers' interrupting "He and four other inmates took turns pissing into the bitch's ocular cavities...This way to the cafeteria!"
