how long has it been since Stan or Kyle said "you know I'v learned something today"

I just relized. I don't think they'v said it yet in season 12, i don't think they said it in the list either

[Jake, Mkay?]

Kyle did in Canada on Strike.

It has been a long time. I hope they say it more often.

It may be that Matt and Trey are passing out of the 'teach morality' phase, can't say I blame em LOL. But I do think that they'll be bringing it back sooner or later as more of a 'teach violence' theme ;)
