Oil Drain Plug....RTV!

I went to do an oil change today....jacked the car up, jackstands, belgian blocks behind the rear wheels, drop light on the Oil drain Plug and I saw RTV caked all over the bolt.

This signified the previous guy who did my oil change when I was busy stripped the threads and sealed it up to mask the issue. Dammit. He wont be getting my business anymore!

What would you guys recommend I do? Replace the Oil Pan? Cut new threads? Use an oversized Honkey-Tonk Bolt and live with a few puddles?

Thanks!
