I have some sweet corn that's about a week or two from being ready to
harvest (I hope). Some of the ears are sprouting what appears to be
"tassles" out them. What are these? Should I worry about them? What
should I do about them?

Snip them off before you cook the corn.

I've had side shoots develop an ear + tassle thing at the tip. I've never had
it happen on a regular ear, though.
