Not overheard, but...

Onions!
From Ithaca Craig's List (CAPS in the original)

I HAVE SEVERAL BUSHELS OF ONIONS. I USED TO FEED THEM TO A FRIEND WHO LOVED ONIONS. SOMETIMES HE ATE THEM STRAIGHT UP RAW. ONE TIME I FED HIM TOO MUCH AND HE GOT SICK AND HIS PORES OOZED ONION JUICE FOR LIKE A DAY. GOOD TIMES. UNFORTUNATELY SAID FRIEND IS GONE. I MISS HIM AND THAT MAKES ME CRY MORE THAN CUTTING ONIONS DOES.

ANYWAY, MY LOSS IS YOUR GAIN. I HAVE NO NEED FOR SO MANY ONIONS ANYMORE. HIT ME UP IF YOU ARE INTERESTED IN THESE FREE ONIONS. I PURCHASED THEM ABOUT ONE MONTH AGO. I THINK THEY ARE STILL GOOD. THEY SMELL LIKE ONIONS. YOU MIGHT NEED SOME ONION GOGGLES, BUT I DONT HAVE ANY.

ONION ENTHUSIASTS/FANATICS/ADDICTS ONLY (IN MY FRIENDS HONOR). WHEN YOU MESSAGE ME, PLEASE EXPLAIN THE DEPTH OF YOUR LOVE FOR ONIONS.
