Fuck off to the sports channels and stay there.
I don't recall anything I enjoy ever ousting sport from the planned TV schedule.
Football: you've got ninety whole fucking minutes. If you can't win a game in an hour and a half, tough fucking shit. The Avengers shouldn't be postponed/cancelled because you useless coiffered rapists can't kick a ball into a big net enough times.
The Olympics: nobody cares about those sports the rest of the time, and they wouldn't now if it wasn't TEH ENGLUND playing. Stay on the sports channels, at 3am.
Rugby: nobody watches this at home. Stick to the pay channels, which the pubs will pay for.
Golf: Get in the fucking sea.
Cycling: Middle-aged men take up cycling to a) get away from their wives, and b ) as an excise to shave their legs. Neither make this a worthwhile audience, unless you also have a range of shitty lycra clothes to flog.
Horse racing: Nobody cares. The audience only care of they've got money on it, and they'll be watching in the bookies. See above re commercial enterprises paying to show it.
Tennis: Just barely acceptable due to Britishness, and being in in the afternoon when nothing of any consequence is on.
In a similar vein, sport on the news. IT'S NOT FUCKING NEWS.
I used to have a signature, but now I don't.
