Garrick gazed forlornly into his pint of ale.  Sensing movement, he looked up to see that a man had sat down next to him.  The man grinned fiercely and clutched a frothing mug of ale still sloshing from recent movement.

“Hellllloooo,” the man anounced, “YOU look like you could use a laugh!”

“I suppose,” replied Garrick.  “It’s terrible: I own a traveling zoo and this morning I found all my hyenas dead and dried up like prunes!”

“Oh,” said the man, grin fading.  “Uh, nevermind, then.”  Garrick didn’t see him slip a corked bottle labeled laughter back into his pocket.
