I brush for like 10 minutes so I can watch tv or dance while doing it.
If you brush more regularly, rather than once every couple of weeks, you'll find that one to two minutes brushing will suffice. However, though I don't know this from experience like you, I'm sure that 10 minutes brushing is necessary to remove all the excess pubes and built-up spunk resin that arise from your day job.
Listerine on the train is pretty funny though. Did you gargle before spitting?
Tell me that you gargled.
Yep. It was only then, when everyone started looking at me, that I realised I was doing a very very weird thing. Before then I figured that women put make-up on in trains all the time, so why can't I get my listerine on in the train?
