Hears his wife screaming, coming from their bedroom upstairs. He sprints up, and opens the door to see his wife laying naked on their bed, sweating and panting.
“Honey! Help! I’m having a heart attack!”
He runs back down the stairs and starts dialing the ambulance, when his son and daughter tell him:
“Dad! Uncle Terry’s upstairs! And he’s naked!”
He slams down the phone, sprints back up the stairs, runs past his wife and opens the wardrobe. Sure enough, there was his brother crouching in the corner naked.
“WHAT THE HELL TERRY! My wife’s having a heart attack and you’re running around naked scaring the kids!”
