Who the hell steals a bike but leaves the wheels?!

[separated by a scream]

That's pretty hilarious! I wonder who would take only a bike frame... My only answer is: an idiot.

Why are so many of you confused?

If someone has a mind to steal something, they're going to take what they can.

What's a wheel or two when you can have a frame? Besides, you have some wheels back at the shop where your uncle Peaches is making corn bread.

While I do think it is stupid, I can almost understand the crooks mentality. A frame will still make money. Wheels can be easily replaced.
