How many Guatemalans does it take to change a lightbulb?

Answer:

- One to tie two rickety ladders together

- Five to climb said ladder and climb head-first through a 16" wide window to enter the building

- Four of the above five to hold a ladder supporting the bulb changer

- One to take out and replace the bulb

- Four to observe the feat (plus four of my students and me - possibly the only thing that could distract us from watching Harry Potter)
