Say what?!

Tayson (singing): "London Bridge is falling down..."
Ruth (thinking): Oh, he's singing London Bridge! That's so cute!
Tayson: "Falling down, falling down...."
Ruth: He must have learned that song at preschool, because I've never sang it to him.
Tayson: "London Bridge is falling down...."
Ruth: I've really been pleased with this preschool that he's going to.
Tayson: "My bare ladies."
Ruth: Which reminds me -- wait a minute, what did he say? "What did you say, Bud?"
Tayson: "London Bridge is falling down, My bare ladies."
Ruth: Hmmmm. Interesting.
