 At least it don't eat
I told my wife that I was thinking about buying another kit and building my son in law a motorized bicycle. That is if nobody else will buy it. She looked at me as if I was crazy so I said, "At least it won't eat."
Now that needs some explaining:
My dad was a big time bird hunter. He had a yard full of dogs, and a garage full of tools. Mom complained about him buying so many tools one time. He told her, "I'll buy all the tools I want. They don't eat." That statement out lived him as my wife and I use it to justify anything we buy just for the heck of it. "Well at least it don't eat." |
