"You came home from work early and found your wife in bed with a
strange man."

"That's correct," replies the defendant.

"Upon which," continues the prosecutor, "you took out a pistol and
shot your wife, killing her."

"That's correct," replies the defendant.

"Then my question to you is," demands the prosecutor, "why did you
shoot your wife and not her lover?"

"It seemed easier," the defendant says, "than shooting a different
man every day!"
