Had a surreal experience on the tram once of which this reminds me.
A guy had bought a can of Coke and was standing in the middle of the tramcar during rush hour, drinking it in the following manner:

1. Take a mouthful of drink by placing your mouth on the perfectly vertical can and applying as much suction as you physically can, allowing your lips to samba about in a rainstorm of drool over the top of the can in the process;

2. Swish the drink around in your mouth;

3. Lift your head slightly and gargle with the now-flat Coke whilst singing a mezzoforte vocalise in the key of G;

4. Swallow and smack your lips as though you have just polished off a hog roast;

5. At no point in the entire process must you acknowledge even slightly the rest of the carriage, staring at you and openly pissing themselves.

That can only have been for a bet
Or possibly a symptom of something

He looked more the symptomatic type than the betting type, to be honest.
Not that the categories are mutually exclusive.
