Anniversary

A couple celebrate their 25th wedding anniversary and their children take them out for a meal.

Later on they are in bed, she's in the mood but he isn't. "What's wrong?" she asks.

"Nothing," he replies

She sits up, puts the light on and asks him again what is wrong.

He replies "Something's bothered me for years now, we've got 6 wonderful children BUT, five of them look similar but our little Tommy doesn't look like any of the others. If after 25years there's something you want to tell me then this is the time."

She takes a deep breath and says "OK dearest, Tommy has got a different father to the rest of the kids."

"WHO???" he asks.

"YOU!!!" she replies.
