Mother Teresa?

Two GIs were wandering the streets of Calcutta when an old woman walked by.

"Hey, Billy Joe," one said, "I think that's Mother Teresa."

"Your nuts."

"I'm telling you."

So they approached the woman and one asked, "Are you Mother Teresa?"

The old lady eyed them scornfully. "$!#@ off, you #@!*! perverts," she hissed, striding off.

"Jeez," Billy Joe said, watching her disappear into the crowd, "now we'll never know."
