A man finds a genie in a bottle
He is granted 1 wish. Being that he is old and has erectile dysfunction he wishes that he might one again achieve the firm erection of his youth. The genie grants his wish on the condition that when he finally decides to get the erection, he has to proclaim 1-2-3! out loud. And then when its time to go back to flaccidville, the words 1-2-3-4 must be said at which point his boner would subside.
