Inauspicious roles early in their careers...

Daniel Craig had bit part in an episode of Drop the Dead Donkey (a show I wish a lot more Dopers had seen).

He play the ‘leader’ of a street gang who gets intimidated buy George (see the link) and made to do the *Chicken Dance *- with full words and actions.

I saw Rob Reiner in a TV episode of the old Batman series. He was a Delivery Boy.

Oh, man, you just jogged something loose: Mark Hamill was a Delivery Boy in an episode of “Night Gallery” (There Aren’t Any More McBanes).

I adore that; sadly the torrent quality is too poor to watch. The glorious Valerie Mahaffey is even more invigoratingly manic than usual.

I also liked Herman’s Head, and loved Dweebs ( but the latter is too sad to talk about, especially since it was cancelled quickly ).
My tastes are modest.

He’s a shy biker on The Partridge Family. They help his gather the courage to hit on the women he like.

Farrah Fawcett is on ep. also, billed as "Pretty girl.
