At last a smart blonde

THE HEART ATTACK

A blonde gets home from work early & 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 dialling, 
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

heartless

Bitch', she screams. 
'My husband's having a heart attack, and you're running around naked,
playing hide and seek with the kids!!'
