There are certain rituals of life that seem to be unavoidable. Often these are family traditions. The family of a friend of ours, for instance, had a habit of making a silly noise every time they drove into a different county.
I find that there are certain encounters that generate a near-automatic response. Whenever I see a particular thing it make me utter a (not very funny) phrase, or burst into song.
Probably the strongest example of this is when we're on holiday in France. There's a restaurant chain there called Buffalo Grill (presumably pronounced 'boofalloh greel') with very distinctive buildings. I guess they're a kind of rib shack, though I've never been in one. But I can't see those big horns without bursting into Buffalo grill won't you come out tonight, come out tonight, come out tonight? Buffalo grill won't you come out tonight and dance by the light of the moon. Sad, I know, but it simply can't be avoided.
Do you have similar automatic responses? What triggers your funny bone? And for your delectation here's one version of the original of this masterpiece with non other than Bing Crosby and Rosemary Clooney. What more could you ask?
