why daddys have beer bellies...... one morning a young boy walks in on his mam bouncing up & down on top of his dad. the child looks horrified and retreats to his room. his worried mother follows the child & finds him looking upset on his bed. "what were you doing??" asks the child. without thinking the mother explains.... "your dad has a very large stomach, so now and again i have to compress it down to stop him getting too fat, hence the bouncing up&down" the child laughs & says "mammy youre so silly!!" "why??" asks the confused mother "because every time youre shopping the lady next door comes round and blows it back up again!!"
