I now (after plenty screw ups) have a "buddy filter" installed in my brain that asks, "Is this something my buddies would like/think funny/etc?"
If "yes", do NOT proceed... DO NOT - do, tell, show, release while in the presence of opposite sex/GF/wife/signif other/etc. There are guy-things...funny as you and I know they are, that just don't translate. Don't fight it.
If "no" - proceed at your own risk, but likely the best course.
FWIW, I understand the whole idling thing outside the house. Sounds good to me, too. <buddy filter disengaged>
ymmv
