Looking for some card game cheats

Nothing specific, I have to write an instructive piece on how to cheat at cards. Its intended to be humourus, er humoros, humouros, er, funny, and not malicious.

The particular games are Poker, 21, blackjack, cheat, rummy, and are ideally for people at home rather than sleight of hand style things.

If anyone can help, I’ll be very grateful :smiley:

…also general things like “accidentally” dealing yourself less cards etc.
