Husband & Wife

A husband and wife were involved in a petty argument, both of them unwilling
to admit they might be in error.  
"I'll admit I'm wrong," the wife told her husband in a conciliatory attempt,
"if you'll admit I'm right."  
He agreed and, like a gentleman, insisted she go first.  
"I'm wrong," she said.  
With a twinkle in his eye, he responded, "You're right!"
