Little Ricky is pulling his pud. Ricky's mom enters and proceeds to give Ricky a talk about masturbation in such a dead-stare way that I'm pretty sure Ricky will never be able to wack-it successfully again.
Of course as a by-product of watching this short video (which was part of a sex-ed film to help educate the mentally-disabled in 1975 called The ABC of Sex Education for Trainables-the fuck?) you too will have much difficulty being able to rub one off as well.
Learning is power people.
Video after the break.
And here's that sex-ed film I mentioned. You might want to get loaded first.
