A note to folks who suspect their spouses are cheating: don’t hide under some stranger’s SUV while playing spy.

Rescue crews freed a woman trapped under a sport utility vehicle in Brookline late Monday morning.

Police said the woman, whose name has not been released, feared her husband was cheating on her. They said she went to spy on him by crawling under an SUV outside her husband’s alleged girlfriend’s house in the 1300 block of Oakridge Street.

She apparently fell asleep under the vehicle and became trapped after someone let the air out of the tires.

Ray Ludchak was working on the house next door when he heard the woman’s cries for help. “I peered down to see a body beneath a vehicle,” said Ludchak.

Police have no idea who let the air out of the tires, but I’m guessing there’s a girlfriend laughing her ass off somewhere about the whole thing.
