Mysterious Nyuks

I think I’m going nuts. Or I really did just hear the first eights of the "nyuk nyuk nyuk nyuk" The Three Stooges are wont to make. Why would someone in the trailer issue such an abortive nyuk? Why are my ears so attuned that I can hear an eighth of a nyuk⁴ at a hundred paces? Yes, I have some Three Stooges DVDs at home, but I can’t remember the last time I watched one of them. And I didn’t watch a lot of them as a kid, either. Oh, a few, but not enough that you think my brain would have a nyuk on an E-Z recall memory circuit linked acutely to my peripheral hearing. Maybe it was just a weird noise, and my brain, seeking to classify that weird noise, went through my Inner Box of Weirdness and came up with a nyuk as a possible explanation.
