More about Spill your coffee.
Right, so, go to your local gas station and get yourself the largest cup of coffee available. Next I want you to pour as much coffee as you can handle down your britches.
You don't HAVE to do it inside the store, unless you're feeling ballsy - but it has to be fresh. In fact I dont know why it has to be gas station coffee, but it's my dare so deal with it.
Don't go trying to find a loophole either, it has to be HOT coffee.
