It's more than fair to say we've all seen some truly unbelievable things -- and people -- on BART. Which is why this video of obviously bored guys really shouldn't surprise/annoy us so much.
Although we don't like some of the things we see on BART, we can still sort of understand the
logic disgusting need: Guy picks his nose because he has boogers; man pukes because he's been drinking too much; woman takes her shoes off because her feet hurt and she's entitled.
But guys falling on BART trains -- and videoing it? Now we're truly stumped.

Update: Apparently, this duo doesn't just fall on BART, but they lick BART, too -- just for laughs.
