Happy Gilmore
is mine, I totally love it - beyond cheesy but great soundtrack and always makes me belly laugh even though I probably know every line in it by now. I think I have conditioned myself to giggle snort every time the golf ball makes the awesome whizz sound.
This bit where Happy hits the golf ball for the first time
never fails to put a smile on my face and tears in my eyes and then it just gets funnier and funnier - a quick mood improver if ever there was!
What movie makes you laugh?
