"Toasts" joke

Having theirr wedding reception in the same
hotel, and the two grooms, John 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 John.
"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?" says John.
"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
grooms are smiling as the waiter comes to take the order.
John 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! "
