Two couples are on vacation in the same hotel. The two husbands, Frank and Dave, are having a few beers together at the bar.
"I bet I make love to my wife tonight more times than you make love to yours," says Frank.
"Never. I'll bet $50 my wife wakes up more satisfied than yours," says Dave.
"Right, you're on. But how will we tell which one of us has won?" asks Frank.
"Easy. When we come down for breakfast tomorrow, just order the same number of slices of toast as number of times you made love," says Dave.
The following morning both couples are at breakfast, and both men are smiling as the waiter comes to take the order. Frank leans over - "I'll have a full English breakfast, and SIX slices of toast," he smiles, winking at Dave.
Dave leans over, and says in a loud voice - "I'll also have a full English breakfast and SEVEN slices of toast -- and make 2 of them brown!"
