Samantha the Bard - S5.E18

Samantha is speaking in rhymes, which turns out to be a bad thing when Darrin is entertaining a client who has been using jingles for years and is tired of them. Larry gets tired of Samantha rhyming and wants her to quit it. Dr. Bombay comes by and gets Samantha to stop rhyming. She then explains to the client that she spoke in rhymes to prove how annoying they can be.
