To the tune of "I wish I was a mole in the ground":

I wish I was a mohel at your bris
I wish I was a mohel at your bris
If I was a mohel at your bris,
I'd cut it off like this
I wish I was a mohel at your bris

Sandek wants a four-cornered shawl
Sandek wants a four-cornered shawl
Put in on his lap,
In case the baby crawl
Sandek wants a four-cornered shawl

I cannot believe that the Mudcat has actually provided a thread that gives me the opportunity to post this parody, which I never thought I'd get a chance to share in public.

Glossary:
Bris or Brith milah is the Jewish circumcision ceremony, held when the male child is eight days old.
Sandek is the person who holds the baby in his lap (or on the table, these days) during the bris.
