Sitting On The Lap

In a crowded bus an older Monk, asked a standing pretty young woman to sit on his lap, which woman did to avoid getting bumped to other opportunists standing around.
In a short while she jumps and stands up. Anxious to help damsel in distress other passengers started watching curiously for what happened?
Embarrassed Monk pleaded, "My child, please sit down."
The angry woman pointed finger and yelled, "Baba, you have to first make IT sit down before I can sit again there."
