Nice! Good one. (I'm nodding.)
However, it may be worth noting that a meme, by its nature, might be navigating the reader to an answer that could be needling, mind numbing, or perhaps even nurturing.

After 3 weeks, it's time to reveal this meme's joke:
Nothing. That's it. "Nothing" is a word that begins with N and ends with G. N-o-t-h-i-n-G
That's the joke. Lame? yeah, I know. Please don't hate me. ☻
NUG! That could be a grunt (low man), a bud, or (the best one) chicken nuggets! YUM! I digress...
Excellent response, perhaps better than the meme's joke "answer" that I will now put in another comment.
