Well, what did you say?

Tell him to try a rim job first

That is some expensive lube your friend would be using, instead of just buying actually lube!

Only if you feel like they've done a lot of mileage.

Hey, whatever gets your motor going is fine by me.

Well...can it?

Rednecks, rednecks everywhere.

If you want to risk getting toxic chemicals inside your body or someone else's, sure. Seriously though. Get on that new friend thing. Perhaps some that are a bit smarter.

I hope you told them yes.
