The 'Fuck You' Laugh

At first I thought it was just one of many adorable behavioral tics the munchkin had as part of his repitoire (like the constant raspberries and the infamous "lipper"). Now I'm realizing that he's definitely mocking me. Picture it, if you will:

Dinner, Tuesday evening. We put the plate on his high chair tray: veggie cheeseburger with ketchup, a potato pancake, and a vegetable medley. Jon gives him a milkshake, which we soon had to pry out of his tiny hands on the condition that he would get it back after he ate some of his dinner. Whining ensues. The munchkin realizes that the return of the milkshake is worth less to him than the amusement of watching his parents totally flip out (which is probably like toddler porn). So begins the 'Fuck You' laugh and accompanying hijinks.

To be clear, the 'Fuck You' laugh is a high-pitched, barely-audible "ha, ha, ha, ha"-sounding fake chortle that the munchkin emits while looking you straight in the eye and doing something that will undoubtedly make you mad as a hatter. Something along the lines of, say, taking heaping fistfulls of vegetable medley and tossing them on the floor. Repeatedly.

I'm wondering if perhaps there's a boarding school somewhere that accepts preschoolers.
