I don't remember who recorded "Bunce the Seadog", about a dachsund mix who mates, very publicly, with an afghan hound. But the first time I heard it, I was on the floor.

Bill Cosby's "The Chicken Heart that Ate Up New York" is another classic, though not a song, it is a recording.

Seumas Kennedy is also pretty funny.
It was interesting watching Azzizi the first time she heard him. I come from a family that told stories like that at the dinner table. I knew what I was in for. Azizzi hadn't been exposed to that sort of humor before. Not that she didn't think he's funny, just that she wasn't quite used to it.
