You've probably heard the never ending "How many -insert profession- does it take to change a light bulb" joke. Now let's make it the Harry Potter way! How many -insert magical creature/Hogwarts professor/anythingyoucanthinkof does it take to light a wand?

There are endless variations that I found on the Internet, so just go ahead and post your favorites if you can think of any new ones!

Example:
How many Dark Lords does it take to light a wand?
Two: One to light it, and one to kill him and take the credit.

How many Slytherins does it take to light a wand?
Two: One to light it and one to blame the Gryffindors in case it doesn't work.

And my absolute favorite:
How many centaurs does it take to light a wand?
None. Mars is unusually bright tonight.
