"Practical Joke" joke

Now, what I did to a guy I didn't like one night is a classic:
I saw him at a restaurant with his "other woman" seated in the corner
of the restaurant trying to be inconspicuous. I went to the head
waiter and told him I wanted to send a cake over to my friend's table
since he and his "wife" were celebrating their 10th wedding anniversary.
If you've ever been to a place like Bennigans where the waiters and
waitresses come singing and banging pots when they deliver a cake to
your table, you can imagine what happened next.
Four waiters and three waitresses carrying a cake with a sparkler
marched over to their table singing "Happy Anniversary, Carole and
Mark...Happy...Happy...Happy Anniversary."
Talk about someone looking for the exits!
