I laugh/giggle at the most inappropriate of times, if something has tickled me i can laugh for ages afterwards, even to the point where i'm crying with laughter, my family look at me as if i'm crazy.
One of these occasions were when i'd watched Inbetweeners (the one where they go on a school trip and Neil punches the fish). I went to bed as normal and as i was dropping off the scene replayed in my head, and i burst out laughing, but it appeared the more i tried to surpress the laughter the worse it got, well safe to say i was laughing for half an hour unable to go to sleep (husband was not happy!)
Oh and when hubby hurts himself i laugh, like on Christmas morning he hit his head on an open cupboard door, and he had a line there for the whole day, everytime i saw the line i could feel the giggles start to develop, in the end i just had to let them all out
And there was a time when i was in a meeting with school regarding my daughters statement of education (SEN meeting), and the educational psychologist had said...."we have a
doody to give your daughter 23 hours of support" so she'd said 'doody' instead of duty, and the more i tried to surpress the laughter the worse it seemed to get, childish i know, but it's hard for me to control!
