Myself a few months into my new role.

I attend the Christmas work event (free bar) and got super drunk. I go the toilet for a piss...

During that time I strike up a conversation with the dude stood next to me and to cut a long story short I end up betting, stake defined, hand shook that the company we both work for will fail within two years due to some governmental reforms I knew little about.

Turns out the dude happens to be one of the board members. Its big company 100's of employees.

There were other employees in the toilet at the time too not 30 minutes later and everyone knew what I'd said. It was rather embarrassing I almost didn't turn up the Monday following.

Not my proudest moment, but thankfully I wasn't fired. Its been 1.8 years... I and still work there.
