I have two words I need you to write down. The first word is "drilldo." Please fold that up and put it in your wallet. The second word is "fucksaw." Highlight it in yellow. Place that in your wallet, also. Should it ever fall out of your wallet and be read by someone, wait for them to make eye contact and answer their unasked question with a sharp nod.
A drilldo is what you get when you put a dildo and a drill together. A fucksaw is what happens when you take something, let's say a saber saw, and jam a dildo on it. It needs to be said, however, that if you were to ever create a Frankenfuckmachine like this, you need to do it properly. When you build such a machine you must build it as an engineer, not as a desperate pervert. Desperate perverts have never contributed anything to the advancement of man, but engineers have. So put on your thinking cap and, this is a freebie from ol' Felix for you, remove the blade first. Don't keep the fully functional, flesh-rending blade of the reciprocating saw in place if you plan to mount a rubber shlong on it and insert it into someone else's orifice. The reason being that you can't put a power tool inside another human without Jesus himself shrieking and turning away in uncomfortable terror.
Despite the obviousness of my engineering advice, back in 2009 a couple in Maryland were all "fucksaw, yee-ha!" and decided to give it a try. Mr. Wizard just jammed the dildo right down over the blade and, surprising to no one but him and his dim-witted yet insufferably horny partner, the sex-o-matic panic machine malfunctioned insofar as the blade just chewed through that rubbery wang like a hyena through a wildebeest carcass and, predictably, went right on into the lady. Did you just make an uncomfortable face when you read that? Yeah. Imagine what her expression was like.
So she had to go to the hospital, because obviously, and we've all just learned a valuable lesson in how not to hump a cutting tool (the lesson is don't hump a cutting tool.)
