Tools/ideas for finding an old game with a weird move beyond the opening?

Okay, so I've probably played too much here, and I was reflecting on some of my favorite games. But they are tough to find.

And I remember one that stands out, not for my brilliance, but for my stick-to-it-ive-ness.

I was playing a pretty strong player, roughly 1700. I had the black side of a French Exchange. I meant to play ...Be7. But my mouse slipped, and I played an unintentional Bongcloud.

After some evasive action, I won the game! I hope it didn't cause my opponent to give up chess. Sometimes it stinks to see your opponent made a bad move or silly opening and fail to capitalize on it. But I remember finding creative, if not sound, moves.

Now--as for finding the game? Chess.com lets you download all PGNs. So I could write a Python script to parse them, and look for "exd5 exd5" in the individual PGNs, with Ke7 occurring before move 20. That would probably narrow things down enough, and the parsing might take a bit of time to program, but it wouldn't break my brain.

But is there a way to look things up in detail on chess.com? You can search by openings and ratings, but I've played a lot of French Exchanges, especially against people rated ~200 points lower than me who (and it's a good strategy) hope to bait me into trying too hard for a win.

Alternately, does anyone have suggestions for refining my script, or maybe they could point me to someone who already did this sort of thing where you can roughly describe a game?

Or do I just have to slug things out with a Python script?
