the heretic genetic algorithm

Gads. I was supposed to be going out with my brother to see the new Guy Ritchie film tomorrow, and he's just dropped the bombshell that instead of being a bro'n'sis night, he's invited his GF along too. Firstly, it was a bro'n'sis night. Secondly, she'll hate it even more than she normally hates everything that isn't vapid and/or pink. Thirdly, they're the most tedious couple on the planet to hang out with because, as I think I mentioned before, they alternately snog to the exclusion of everyone else, then have nasty vicious rows.

And he's already bought tickets.

Is it wrong to pull a sicky? It's worth 7 quid not to have to waste an evening I'd rather spend at home with 0ct0pus and the midget.
