In the produce department of the local supermarket the other day, The Space Cadet was almost run over by a lady who had been shopping for citrus fruit.
Space Cadet: Madam, I hope you've got a valid driving license for that vehicle. You're dangerous!
Shopper: They let me out on the roads with it occasionally, but this isn't much of a car, it's got a wonky wheel!
Space Cadet: Well, don't look now, but you're driving a lemon!
