Given the interest in limericks of several members of this site, this might be of interest, describing where a contestant is asked to rhyme distraught, brought, and hot. Phonoloblog.
(Hat-tip: Literal-Minded)

That's one of the well-known problems. Some time ago I was given a present of a rhyming dictionary but I have to be very careful in places because it's American and a lot words listed as rhyming in there just don't for me. Because it's an area I'm familiar with I might have guessed the last line but for me it could never actually rhyme.

Ah, yes, I often listen to that limerick rhyming on "Wait Wait Don't Tell Me!" They're usually very easy, but sometimes situations like this occur. I think I remember this very one.
