A blonde gets home from work early and hears strange noises coming from the bedroom.
She rushes upstairs only to find her husband naked lying on the bed, sweating and panting.
'What's up?' she asks.
'I think I'm having a heart attack,' cries the husband..
The blonde rushes downstairs to grab the phone, but just as she's dialing, her four-year-old son comes up and says,
"Mummy mummy Aunty Shirley is hiding in the wardrobe and she has no clothes on".
The blonde slams the phone down and storms back upstairs into the bedroom right past her husband....
Rips open the wardrobe door and sure enough, there is her sister, totally naked and cowering on the floor.
'You rotten Bitch', she screams.
'My husband's having a heart attack, and you're running around naked playing hide and seek with the kids!!'
