Uncle Meat, Burnt Weeny Sandwich and We're Only in it for the Money are my three favourites, though I also have Tinseltown Rebellion. I liked the episodic nature of some of the writing; the alternately crazy, rude, challenging lyrics; the cut and paste montages; the use of percussion and treated vocals...
Once he became serious and wrote 'proper' music with too much guitar, I must say I lost interest. I've turned prude too, and his endless satire on attitudes to sex became tiresome. Having said that, I recently recorded a concert off the TV - The Torture Never Sleep - and was very impressed at the musicianship again.
He's not constantly on my 'turntable', but I'll not be getting rid of my CDs any time soon.
