Well, there's always the 'possessed' chair.
It starts to *cough* levitate and play Rammstein backwards while copious amounts of stage smoke billow out.

C3PO used one of our possessed chairs in Return of the Jedi when he was talking to the Ewoks and Luke levitated him, so he can give a testimonial as to the effectiveness of our products. And then there's the whoopie cushion chair :)
