Unfortunately this reminds me of a foul practical joke my friends played on one of our unsuspecting acquaintances who happen to pass out drunk in the park with a half drunken quart of bud beside him. He woke up and it was full and he polished it off not knowing. I felt for the sake of peace, as he was a maniac, it was better to mind my own business and not say a word. Ahhhhhhh the good old days.
