I once played Deal or No Deal with a client. We played the interactive game on his telly and every time I lost, he would have me do some strange things. This included things like balancing on a ball, whizzing around in one of those vegetable racks with wheels, playing see-saw on a makeshift see-saw made out of an old ironing board and riding around in an old pram. Oh, and I had to burst a grapefruit with my arse.
It was one of the most entertaining bookings I've ever had.
