THIS IS WHAT MAKES ME LAUGH!
Great theme for THIS IS... this week! What makes me laugh more than anything is other people with infectious laughs. You only have to put on The Laughing Policeman or one of those 1970s Smash mashed potato ads with the laughing martians, and I'm off!
No-one has a more infectious laugh than Sid James in the Carry On films though. Just hearing this one second clip makes me giggle hysterically. Check out this classic clip from Carry On Camping where he has taken his wife and friends to see a film about nude camping without them knowing! Hee hee!
