"Had this happen more than once during my golfing days," wrote John Yancey. "After I hit another terrible drive, a crow would comment with the usual 'Caw, caw, caw.' Only it would sound to me like: 'Haw, haw, haw.' Then I would look up and say: 'Well, I bet you couldn't do any better.'
"Speaking of laughing birds, I was recently listening to a nearby robin voicing a rapid series of staccato notes. This happens frequently in the evening, and I guess it's some sort of territorial warning. But if you listen for it, it can sound like rapid laughter after hearing a particularly funny joke. So it made me wonder what sort of joke would strike a robin as funny."
So Yancey wrote a bird joke. Here it is.
First robin: "How many sparrows does it take to change a light bulb?"
Second robin: "I don't know, how many?"
First robin: "Sparrows don't have light bulbs, They're too cheap, cheap, cheap. Yuk, yuk, yuk, yuk, yuk, yuk."
