Boo Bees

My wife gave me a Valentine's Day card that was just a bit silly and just a bit risqué.  Eryn asked if she could see it, and originally I said "no, it's for adults."  Then I thought about it and said, "Sure, go ahead."

Eryn: "I don't get it."

Me: "What are they?"

Eryn: "Bees."

Me: "What are they saying?"

Eryn: "Boo."

Me: "And what are they?"

Eryn: "Bees."

Me: "What kind of bees?"

Eryn: "..............bumble bees?"

Me: [laughing] "What are they saying?"

Eryn: "Boo."

Me: "And they're....?"

Eryn: "Bees."

Me: "They're...?"'

Eryn: "Bees?"

Me: "That say?"

Eryn: "Boo."

Me: "And they're?"

Eryn: "Bees."

Eryn: "Boo. Bees."  [Eyes roll.  She gets it.]
