Least rewarding thing you've ever done to your parents?

[The Clown of Pevensey Bay]

Saw the other thread and felt left out cos I haven't got any kids.

I managed to get my dad prosecuted for TV licence evasion. Picture the scene when the licence inspector woman knocks on the door.

Her: "Hello Mr Ofpevenseybay, why haven't you got a TV licence?"
Him: "Because we haven't got a telly"
Me: "Yes we have, I've just been watching Mysterious Cities of Gold!"

My dad paid the fine before it got to court. Serves him right as I now work for the BBC

Looked after their house for a couple of weeks one summer, managed to break the tap in the kitchen sink, the water wouldn't turn off and it kept running...had a clever idea that I could turn off the stop-cock under the sink, it wouldn't budge so I dug out some stilsons from the shed, snapped the bloody handle off...spent the rest of the two weeks using the stilsons on the brassy stump each time I needed water. Parents returned from holiday, got a bloke round to have a look at it, ended up getting a completely new supply pipe all the way out to the valve in the road...the pipe actually went under the house so it wasn't a minor job.
