|Holmes and Watson|
"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 one hand and pushed her head toward it with the other."
