Tuxedo Trick

A friend got married and I, being the best man, decided a humorous practical joke was in order. One of the duties of the best man is to make arrangements for the pick up and return of the groom's tuxedo. After final fitting, rent an extra coat jacket that is either three or four sizes smaller or larger than the groom's. Explain to the tux shop what you're up to. Pick up the groom's fitted coat, switch with the extra rented coat, and deliver to the groom only when it becomes time to actually get dressed. The friend of mine wore a 42 long, but the one I provided was a 38 short. Talk about some serious fun!
