Suit's you, Sir!
Seat everyone in a circle. Leader stands in the middle with an ordinary pack of cards.
Name everyone in the circle for one of the card suits - Spades, Clubs, Diamonds, Hearts, Spades, Clubs ... and so on. (If the number of people divides exactly by 4, add an empty chair to the circle)
When everyone is named, the Leader turns over the first card and calls out the suit - say Clubs. All Clubs move one seat to the left. This will mean they have to sit on the lap of the person next to them!
The Leader calls the next card and the people named for that suit move, and so on.
The winner is the first person back to their own seat.
HOWEVER, you can't move if there is someone on your lap, and if there are 4 or 5 people on your lap, you are stuck for ages! I have seen queues of 10 people all 'sat' on one poor person!
