A man stumbled up the stairs to his bedroom in the wee hours of the morning and was greeted by his very irate wife.
"Where have you been?" she demanded.
"I was over at my buddy's house," he mumbled.
"You are such a liar!" she yelled. "I can smell perfume all over you and your face is covered with lipstick. How dare you tell me you were at your buddy's house?"
"Look, honey," he replied, "if you don't believe me, go ahead and call any of my buddies. Any of them will tell you I was at their house."
