I haven't in public, only when I sleep
However, my dad's a mean ass fuck. When he was in school, he had this girl who was a bitch to him and loved to embarrass the fuck out of him every chance she got, so payback's a bitch. He went and smashed up some cherries, when she was wearing white pants, etc., and he placed the juice in her seat and she sat down and didn't notice, but when she stood up, everybody noticed her supposed "accident" . She never knew it was my dad, but she never messed with him again...
