Funniest moment I ever had at work was when we were in a training session for our Data Warehouse.
The chap training us had taken us out for lunch at the pub, and he had the Chicken Burger. We got back to work and he disappeared for about 10 mins to the toilet.
We were getting a bit worried about him and said I wonder if the Chicken Burger disagreed!!
He comes back into the room and says "crikey that toilet took some filling"!!!
Cue hysterical laughter from all of us
Looking rather embarrassed he explained that he meant the flush wouldn't work!!
Still tickles me even now.
