Going back to queueline farting, probably my favourite experience at Thorpe Park was picking on a young man who dropped a particularly bad one in the "I'm a Celebrity" line.
My nephews partner blamed my nephew, he denied it in a very loud voice, and I saw a young chap ahead of us shrink down.
So I pointed him out and shouted "It was that filthy blighter over there, in the yellow T shirt". The guy with him fell about laughing, and I continued a loudmouth rant until the queue manager strolled over and joined in as well, giving the air a sniff and agreeing that he was indeed the guilty party, whole queueline starts tittering.
Nothing like a rancid stink to cheer up a slow moving queue.
Then we quit the queue and went back to the coasters.
