"I've got a feeling that my wife is having an affair with the milkman." said Bill.

"What makes you think that?" said Ben.

" I happened to look under the bed this morning and I found six bottles of milk."

His two friends were taken aback by his confession.

"Well" said Harry cautiously "I've got a similar problem myself. I suspect my wife is having an affair with the postman."

"Are you sure?" said Bill, sympathetically.

"I think so." he replied. "This morning I happened to look under the bed and found a bundle of letters."

"Well."  said Ben, who was 'not the sharpest knife in the box. "You're not the only ones with domestic problems."

"Is it your wife? they enquired.

"It is indeed." replied Ben. "I'm sure she's having an affair with a reindeer."

"A reindeer? What makes you think that?" they said in astonishment.

"There's no doubt about it" he replied "I woke up on Christmas morning  and found Father Christmas under the bed."
