I once went to pick up a "free 36-inch Weber", worried that I might not be able to fit it in my car. Turns out it was a 22OTS, but the dude was measuring *the height*.
(The other funny thing was that he was getting rid of his kettle because he had a new smoker-- a 7-foot long barrel-type smoker. He was bleary-eyed from tending a very demanding 16-hour single butt cook the day before, and was grumbling about how much his temps were jumping all over the place and how he needed to constantly feed the fire. I didn't tell him I was taking away a far superior smoker. A few days later it was an OTG and all clean and turning out great pork shoulder for my friend. Silly Craiglisters!)
