Today's award goes to a biologically clueless pet owner in Britain.
An unsuspecting pet owner had the shock of his life when he thought caring for his two new little female guinea pigs would be a breeze.
It turned out that he couldn't have been more wrong. He'd accidentally bought a male and a female, which began multiplying "faster than he could react".
Before he knew it, the babies had mated with one another, and he had 160 little guinea pigs running around in his garden in Gosport, Hampshire.

I'd have thought that when the first litter of guinea-piglets appeared, that would have been what the professionals call A Clue . . . but to wait until he had 160 of them before figuring it out? Verily, the mind doth boggle!
