PEMBROKE PARK, Fla. -

Scared by that mysterious "bump in the night" while sleeping? Don't worry, send the wife to check it out.

A new Yale study found that 1 in 5 men would send their wives to investigate strange noises coming from outside the bedroom.

What's worse, a quarter of the men said that when they hear noises, they pretend to be asleep to avoid having to leave bed.
