Greatest cameos?

[Vraille Darkfang]

Doogie in Harold & Kumar go to White Castle.

Actually Neil Patrick Harris had of a minor role than just a cameo, but it was still hilarious.

 

[John Crichton]

Tarantino on Alias in season one.

 

[Queen_Dopplepopolis]

Tarantino on Alias in season one.

He might be even better when he comes back in season three!

((Oh - Alias - your plot twists are so predictable... but I don't care... I love you anyway!!!))

 

[John Crichton]

The S3 cameo was very cool but the fight in front of the safe with Syd and his 'kickboxers' snipe was classic.
