Why do Spiders have a Wobble?

[Pythonfriend]

i think the punchline is that THE SPIDER GENE IS THE WOBBLE.

also, when you combine a gene with a little bit of a wobble (for example champagne) with a gene that has the real wobble (spider), you hit lethal combos. Thats the second punchline.

edit: with lethal combos i mean: they may or may not hatch, but will soon die if they manage to hatch. living temporarily, but not viable.
