One of the best ones I heard, was to do the following:

During winter time in any part of the country where it gets really
cold, take your victims mattress, soak in water until it has reached
it's saturation level, then hang it outside until it freezes solid.
Once solid, replace on the victim's bed and make the bed up to look
like normal. Boy will they be surprised when they go to bed.
