After a big night out on the town, Bob staggered into his house and tip-toed up the stairs to avoid waking his wife, Kathleen.
On his way, Bob tripped on a step and fell on his butt. He had a small whiskey bottle in the back pocket of his pants, which made the landing especially painful.
He stifled a scream, pulled down his pants and looked in the hallway mirror to discover that his bottom was cut and bleeding.
Quietly, he managed to find a box of Band-Aids in the bathroom cabinet. He placed a Band-Aid on each place that he saw blood.
When Bob woke the next morning, he saw Kathleen staring down at him. “You were drunk last night, weren’t you?”
“What makes you say that?” Bob blustered.
Kathleen answered, “Well it could be the broken glass, it could be the trail of blood through the house, it could even be your bloodshot eyes!”
Bob became sheepish.
“But mostly,” she continued, “It’s all those Band-Aids on the hallway mirror.”
