For you fellers who may wind up in prison take note: Courtesy flushes are mandatory, or your ass will be plugged via bubba! No kidding, some of those guys take that shit seriously.
What about the cover flush? Another prison technique is to flush, right at the moment of the assplosion, to cover the sound.. You let go at the right moment, and all the noise, smell and turds get flushed away at once. Only downside is the need to flush again after wiping.
I do the cover flush all the time. I sure wish my wife would learn it.
