who does this joke and how does it end?

The set up is something about naming something his "manhood" and the punchline is "so that I can say at least I got my manhood" or something similar to that. If I remember correctly it's Steven Wright or Gilbert Gottfried or someone similar to those guys.

It was Mommy. The punchline was "Go put your petticoat on, Bradley"
