Knock knock. Who's there? Sew

Sew who? Sew long, I've been trying to weave a good joke together.

Knock knock. Who's there? Sherwood.

Sherwood who? Sherwood you let me in, it's chilly out here!

Knock knock. Who's there? (Knock knock.)

(Knock knock) who? Oh, for goodness sake, you just started the joke again! This is an endless loop!

Knock knock. Who's there? Otto B.

Otto B. who? Otto B. a crime if you didn't laugh at that groan-worthy pun!
