The Crazy Gang did a good one with Bud Flanagan in eastern costume with a peculiar sort of wand.

Bud; I'm a mystic.
Ches; What have you got in your hand?
Bud; Me stick!
Ches; No, what have you got in your other hand? (Bud's other hand was kept behind his back.)
Bud;(ignoring question) Would you like your palm read?
Ches; (holding out hand) Yes please!
Bud produces large paint brush full of red paint from behind his back and applies it to Ches's hand.

I remember Bernie Winters pulling that one on Michael Parkinson. The expression on Parkie's face was almost as outraged as when Rod Hull's Emu had a go at him.
