I once filled a guys car with live crickets once, as a joke. 'Went to the bait shop and got a double load, then dumped them in his open window at lunch. I heard he got as far as the interstate - when they started to come out of every crevice in the interior....
Later, I realized I was lucky he wasn't killed. I mean, can you imagine, careening down the highway when you realize you are sharing your car with a load of jumping insects....
