The great mathematician and comedian Tom Lehrer wrote the following song about Thanksgiving (to the tune "We Gather Together"). As usual, he makes fun of something a lot of people can identify with. For another example, see A Christmas Carol.

We gather together to ask the lord's blessing
For turkey and dressing and cranberry sauce.
It was slightly distressing but now we're convalescing
So sing praises to his name and forget not to floss.

Our nearest and dearest we don't want confessing
It's sort of depressing to have them so near.
Our feelings supressing for lightly acquiescing
And perfectly professing we're glad they were here.

We gathered together and got the lord's blessing
Of course we're just guessing 'cause how can you tell?
Our stomach's are bloating, our kidneys nearly floating
Hellos are very nice but goodbyes can be swell.
