random story from childhood

You know that joke in which you stand behind someone and ask him/her to start listing the months of the year?  "January, February...  MARCH," and then you knee them in their ass?  BECAUSE THEY'VE ASKED YOU TO MARCH INTO THEIR ASS.

Well, I just had a flashback to middle school when I used that joke on my mom, because tonight she asked me to massage her shoulders while she slept while standing like a horse, and here was another perfect opportunity to get her.  Why and how did I use that joke on a mom who didn't know English 10 years ago (she doesn't know much English now either)?

Hot Springs, AR, 1997:
After my sister got me real good with her knee upstairs minutes ago, my mom and I were both in the kitchen and I went up to her at the stove and said:

me:  Hey Mom, start counting the months in English, starting from January. Hehehe.
Mom:  Leave me the hell alone; I'm busy.  *stirs mystery Korean stew in pot*
me:  Okay, okay, I'll just start counting for you: "January, February...  MARCH!"  *my knee in her ass*

This was before she adopted a sense of humor to get her through the times when my sister moved out TWICE during high school.  I should've known better...
