　　Ah, this is what we personally call "The Peace Sign at Someone Else's Expense." How does one make bunny ears? The forefinger and middle finger are still involved but, this time, one places them on top of someone's head. Annoying little cousins, bratty siblings and pranksters are notorious for doing this. Perfectly stable and responsible people also do this especially while goofing around, say on road trips and at parties. A word to the wise: Though massively tempting, never attempt to make bunny ears on your boss. Or worse, on your prom date.
