Barry was seated in a tram when a young lady,
looking a little uncomfortable, asked if she could
have his seat.

When Barry asked why she replied, "I am pregnant".

Being a thorough gentleman he immediately relinquished
his seat. However, he did have reservations and asked
her, "How long have you been pregnant?"

She replied, "About 20 minutes. It knocks you around
a bit doesn't it?"
