We do nothing of the sort.
Oh, you mean “checks”! Those, yes. 
I’d love to hear what they were. Do tell!
I learned that some traffic lights only activate when an induction loop embedded in the roadway recognizes that there’s a car waiting. There is an intersection a few miles from where I live that I always used to dread turning left at. It seem like half the time the left green arrow would not activate no matter how long I waited. Now thanks to the SDMB I know that I have to pull all the way up to the stop line if I want the system to know I’m there.
I learned how to tie my shoelaces. (I’m 63).:dubious:
I didn’t know why some Flamingo’s are pink and some are white till I read it on SD last year.

And of course the whole pineapple thing.
Not too often. I probably average two a month.
I learned more than I ever wanted to know about uses for paper towel tubes.

I have to give up on this one - no one here seems to know that they’re supposed to do that.
Avoid, if at all possible, being struck by a dildo wielded as a bat (thanks Zebra)
That a list must be at least three-items long in order to be considered such (thanks Opal R.I.P.)
Male pigs really do have corkscrew shaped penises.
Absolute rubbish. When kids in the UK/Aus/NZ grow up on a diet of Sesame Street, you have to re-program them (the kids) to sing the Alphabet Song with a ZED rather than the rhyming ZEE.
It’s a royal pain in the arse to keep correcting them, but we have to keep the integrity of the Queen’s English, right?
Please note, however, that an “exchecker” is a person who was formerly a cashier.
As of today, I know what “Honeymoon Cystitis” is.
You can buy one with a cord reel.
Oh you can make raisin wine. Just add water … :rolleyes:
Giraffes have a prehensile tongue.
