About three weeks ago, a new brownie shop near us was having a deal. Buy two, get one free. I put the third frozen brownie in my office freezer (a mini-fridge freezer, not a full freezer), intending to eat it the next day, then completely forgot about it until just now.
It’s currently sitting on my desk cooling off after a 30-second defrosting stint in my microwave. It smells good. Should I eat it?
Why wouldn’t you? What could go bad in a freezer for 3 weeks to a brownie? Snarf that sucker down!
Eat the brownie! 3 weeks in the freezer isn’t going to cause any harm.
Definitely, unless it’s freezer-burned to hell (pale brown, leperous)
We routinely freeze surplus brownies, and you don’t even have to defrost them to enjoy!
Why not? Now, if you failed to wrap it up at all it will probably taste kind of funny, but there’s nothing actually wrong with it. Eat it up.
Three weeks? No problem.
Three months? It would probably be covered by frost and you’d have to chisel it out, anyways! 
I think it was “Buy two, get one freezered, be too scared to eat it and buy another two. Get one freezered, be too scared to eat it…”
For that matter, it’s entirely possible the thing would have been safe to eat (albeit stale) after three weeks in a dry cupboard without freezing at all.
Now I have that song from Reefer Madness: The Musical running through my head. “Eat the brownie … eat the BROWNIE …”
NOOO!! Don’t eat it!!!..send it to me instead.
Why did you defrost it, though? Frozen brownies are delicious.
Hell, with brownies, you don’t even have to cook them to enjoy!
I’m stuck on the idea of a brownie shop. I love me some brownies, but a whole shop, just devoted to them? That’s awfully specialized.
It’s next to the Scotch Tape store.
Three weeks in the freezer? I’d eat it after three weeks in the fridge. Hell, I’d eat it after three weeks on the counter if it wasn’t moldy. This is all hypothetical, of course, because I don’t think a brownie’s ever made it to three weeks around here. 
My personal favorite is the Drunken Chunky.
That reminds me of the time I sent my brother’s family a box of live lobsters for Christmas. They cooked them and ate them the same day. A week later he called and asked if it was safe to eat the leftover lobster meat.
I didn’t understand the question.
Thanks for the reminder…and the recommendation. I work a couple of blocks from their downtown location. I’ll walk off the calories walking there and back, right? 
ETA: Forgot to answer your question: definitely eat it.
I trust that by now the brownie has been scarfed down Drain Bead. If not, you don’t deserve it and should send it to me.
Yeah - oxymoron.
