How do you use the can? Hmmm, well you first unbuckle your belt and undo your zipper, pull down your pants and sit. How long do you call for? Hmmm, well it depends on if your wife/girlfriend is in there first and what she may be doing. How long of a wait between calls? Hmm, well depends on how bad you truely have to go....LOL I couldn't resist!

2 bleets back to back and the third one about 15 seconds following the 2nd. Sit back and see what happens.

Good luck!
