Things you find woefully unfunny, but other people like.

Anything with Miranda Hart in it. I can't stand her at all, she isn't funny and she annoys the hell out of me.

Friends. I never managed to get 'into' it or see what the massive appeal of the show was and found the comedy unfunny and the laughter track over all the 'jokes' put me off completely.

Gavin and Stacey (James Corden and Matt Horne just aren't funny), anything that involved Rob Brydon (I find him just awful), Him&Her on BBC3 with Russell Tovey, Mighty Boosh, Extras and The Office...
I remember as a reward for us all working so hard during GCSE French lessons and progressing way ahead of expectations, we were 'rewarded' with 2 episodes of The Office... I genuinely asked if there was some work I could go and do in the library...

Oh, and The Simpsons... saw one not too long ago where Homer rammed a police car with a bumper-car and I genuinely felt that anyone who laughed at that needed sectioning...

Oh, and Borat

-Spaceballs (even though I love Star Wars)

I'm not disagreeing with you here(no, seriously, I'm not) I agree with you that a lot of SpaceBalls is unfunny, but it does have a few moments of pure awesome.

I direct you towards the whole "surrounded by ass-holes" scene, and the password sketch.

Aside from that, yeah. Pretty much Spaceballs.

Also for me :

Family Guy
Most American Comedy
Big Bang Theory
The Inbetweeners
Misfits.
