How do you stop a dog from humping your leg?
Pick him up and sick his dick.
Listen up, lil' buddy. The joke is, instead of stopping a dog from humping your leg, you just grab him and force his lil' dog pecker. This ain't funny to you because, like the author, your humor is as dry as a saltine cracker.

I took your advice and tried, I would like to point out for any readers of this joke that this does not work. In fact, PETA saw me using one of their many wires and then killed my dog and then sucked my dick so I could feel how the dog felt.
