I once saw an episode of Mr. Bean (Yeah, I know. I was bored) in which he played a construction worker. When the lunch whistle blew, he began to assemble a sandwich from dozens of tiny boxes and bags secreted around his person.
He carefully sliced fresh bread, measured out mustard and mayo, meticulously mixed and measured each component, until he finally, finally had his sandwich ready, when the whistle blew again... and he dropped it!
OK. Silly exaggeration, but I often feel that way when I'm fiddling with my pipe.
I still love Columbo, by the way!
