On a beach crowded by a lot of moms with babies a lifeguard accompany a blind man to a safe place near the sea where there are a beach umbrella and a crib. The lifeguard beeing sure of the safeness of the blind man leave him alone.
After some minute, spent to analize the situation thru the sounds and rumors around him, he take out a blanket and cover with it the crib, than he take out a roll, open a valve and begin to inflate it.
A pair of minutes after he has begun, an embarassment sensation spread on the beach, with the moms scolding the little boys or commenting the situation, without know what to do. The poor man is inflating an exagerated rubber doll. The moms of course do not want to embarass the blind man, but at the same time they need to stop the spectacle.
At the one of the moms ask to the lifeguard to intervene to stop the poor man, and the lifeguard kindly explain the situation to the blind man, who, red in face and embarassed over all imagination, rapidly deflate the doll, and in a moment of loss said "Ohhh God, does this means that for all the winter I fu***d the airbed?"
