The pregnant woman in the meat shop!

Nine months pregnant with twins, I bellied up to the supermarket meat section in search of the perfect roast.  The butcher appeared from the back and asked, " May I help you?"

No, thank you," I said.  "I'm just looking."

A minute later, he returned.  "Can I help you?"

"No I'm just looking," I repeated.

A few minutes later, he appeared yet again, asking the same annoying question.

"I'm just looking!" I said testily.

"In that case ma'am," he said politely, " would you please step back a bit?  Your stomach is pressing our service bell."
