The size of Pringles Cans...
Well, two associates were in the lab, and without my "input", have determined, again withOUT my assistance, that Pringles cans are three, yes,
3 -- count em -- well, their 2 plus one of the guy's dildos I guess -- did I mention I wasn't asked to participate in this Government funded pork barrel experiment -- oh wait, where was I ... ah yeah, Pringle's cans are 3 dicks wide!!!
So, go grab a tube of Sour Cream n Onion, a few 12 packs of Milwaukee's best beer, invite two of your best buds over, and estimate it yerself.
Have fun!
