Cleaning out an improperly uninstalled mod

I recently installed, and subsequently uninstalled, DJ's AME because of various reasons. Unfortunately, even though i ran the cleanup tools with the plugin it left behind a ton of artifacts in old posts.

All of my old Youtube video links (which were previously just the YT URL) now look like so:

[ame="http://www.youtube.com/watch?v=6fOprNSFCX4"]Title of Video[/ame]

And since I don't have an AME code, they just parse as plain text. Is there a quick and simple way to clean these up across my forum? I'd like to remove the bold bits, and just leave the URL behind. Bonus points if the URL is still parsed correctly so that it's click-able.

I've attached a screenshot of how it's looking on my forum at present. Any insight would be awesome. Thanks!
