Wardrobe
Dave gets home early from work and hears strange noises coming from his bedroom. He rushes upstairs to find his wife naked on the bed,sweating and panting. "What's up?" he says. "I'm having a heart attack", cries his wife.
He rushes downstairs to grab the phone, but just as he's dialing, his 4-year-old son comes up and says,"Daddy! Daddy! Uncle John's hiding in your wardrobe and he's got no clothes on!"
Dave slams the phone down and storms upstairs into the bedroom, past his screaming wife, and rips open the wardrobe door.
Sure enough, there is his brother, totally naked, cowering on the wardrobe floor.
"You b@stard", "says Dave,"my poor wife's having a heart attack and you're running around naked scaring the kids!!!
