A Sherlock Holmes joke

[note: a bit in the risque side]

"Good evening ladies", Sherlock Holmes said as he passed
three women eating bananas on a park bench.
"Do you know them?" Dr. Watson asked.

"No", Holmes replied, "I've never met the nun, the
prostitute, or the bride we just passed."

"Good Lord, Holmes, how in the world did you know all that?"

"Elementary, my dear Watson. The nun ate the banana by
holding it one hand and using the fingers of the other
hand to properly break the fruit into small pieces."

"The prostitute", he continued, "grabbed with both hands
and crammed the whole thing into her mouth."

"Amazing!" Watson exclaimed. "But how did you know the
third was a newlywed?"

"Because she held it with one hand and pushed her head
toward it with the other."
