A New Year Vignette

Imagine a crowded family room full of people; not enough chairs for everyone.  There were a lot of people in their 20's; the oldest was in his 80's and the youngest in single digits.  Three nephews sat slouched in an uncomfortable short sofa.  Next to them sat an older man, somewhat deaf, in a recliner.  All three nephews are looking down at something - was it their food or their phones, I can't remember.  One nephew quietly mumbles softly, "Menomena."  The two nephews to his right, while still looking down simultaneously tilt their heads to the right and respond, "Dee Dee," tilt left "Dee Dee Deet."  After a 3 second pause the single nephew repeats, "Menomena."  The two nephews on his right respond (right) "Deet Dee" (left) "Dee Dee."  Again, an unusually long pause passes before the first nephew mumbles quietly, "Menomena."  As I and the older man look on with a look of confused amazement, the two nephews respond with heads tilted right, "Deet Dee Dee Dee Dee," tilt left "Deee Dee Dee," tilt right "Dee Deet Dee," tilt right, "Deet Deet Dee Dee Dee Dee."  There is a small smattering of applause and the nephews look up and seemed surprised anyone heard them.  But not everyone did hear them.  A quarter of an hour passes before the man in the recliner asks the three nephews if they can do "that head tilting thing" again.  It's doubtful he heard a single note of the song but he enjoyed the performance anyway.  The nephews decline to repeat their act claiming they can't do it on request, only when inspired.  This ends one vignette from our family holiday.
