It's a picture I came across while searching for the "Hot Wad" ......that's Meatwad's Hot Rod. Thank you for taking my poll, although I think we might both be confused now
You know as soon as I get to the privacy of my own computer at home, I'll be Googling Hot Wad.
I think someone may wear a backpack while naked because they need a place to put their animal crackers and rolls of quarters for the laundry. Neither one of those things would be very comfortable to have wedged up your pooper.
I don't want to be master of the obvious here, but The North Face would sell a lot more backpacks full of key lime jello with this form of non-traditional marketing.
As long as there's no starfish visible, no uncomofrtable stretching, this can work.
