I'm not a huge fan of gender reveal parties, but if I ever had to do one, I'd probably shoot myself with a paintball gun filled with blue paint if it's a boy, and if it's a girl, I'd use a real gun.
Me doing that trick where you wiggle a pen between your fingers to make it look soft with but with my penis.
But its accualy soft and i dont know how to do the trick.
And thats how i lost my job as a children's magician.
