Q: How many gypsies does it take to change a lightbulb ?A: None, but you lose a lot of light bulbs.Note: None because gypsies don’t have mains electricity, and the losing is a play on the larcenous reputation of Gypsies. You give a Gypsy a light bulb and ask him to change the hallway lamp, pretty soon you have one less light bulb and the hallway lamp is still out.)
