God, I stink. I really need to take a bath.
Is there a reason you haven't taken a bath?
I've just been too busy overall.
It's understandable to be busy, but personal hygiene is important. Set aside a few minutes to take a short shower and you will feel (and smell) a lot better.
Showering is for chumps. I like to work up a sweat day after day.
I don't really agree about showering being for chumps but not taking one can make you unpleasant to be around if you've been sweating. I find baths really relaxing myself.
