Baby carriages can be very useful

My supervisor was walking home from work one day and he was having trouble getting across a busy street, because the cars would not stop.

A homeless guy came along pushing an empty baby carriage.

"Do you want to cross the street?" he asked.

"Yes," my supervisor said.

The homeless guy rolled the baby carriage out into the middle of traffic and the cars squealed to a stop.

"They think it's a baby! the homeless guy said. Go ahead and cross the street."
