If you need something to kill time while you’re supposed to be working, now you can have an afternoon laugh with this pair. Just set them up and let them race after each other. Now all arguments can be settled with these guys. All you have to do is say whose ever Grandad wins, wins the dispute as well. To make them go, just pull back and off they go, oxygen tanks hoisted to the back and everything. To pick up a set it will cost you $12.
