"22-inch wheels? Sounds like a dimension to me."
- Haven't you ever built a model? The Hummer in question most certainly could have had 20" wheels...just 1:12 or 1:16 scale. Not disclosing the scale of the vehicle is the whole purpose and punch line of the joke.
Lets say I run a hardware business and I hold a contest (even on April 1) that states for the 100th customer of a purchase of 20 dollars or more will get a new riding lawnmower. I include in this advertisement the name/model of this mower and even throw in the seat dimensions. Whooohooo... you are the winner with pictures and all. However, I present you with only a 3 dollar model of said mower and post your pic on my website portraying you as an idiot.
Do you think you should have received an actual riding mower?
