69
Twenty. 1 to drop it, 19 to go "Pick it up, pick it up, pick it up".
Just two, as long as they can find a way in.
Two, one to change the lightbulb and another to show one they changed earlier.

70 because after 69 your mouth's full.
Hehe... 'screw' Alternatively: 69, but everyone expects that one.
One. But it takes the whole emergency room to remove it.
An alarm, you pervert!
