Look at
this page and see if you can find the receptacle that matches your funky outlet. If you notice from that page, the 20 amp, 110 volt receptacles have one prong turned sideways. If this is what you have (
AND THE VOLTAGE ACTUALLY MEASURES 110 VOLTS), I would think you could replace it with a standard 110 volt receptacle. Note that the 110V, 20A receptacle on this page actually takes either a normal (15A) plug or the 20A plug with the sideways prong.
If your "funky" outlet matches any of the 220 volt receptacles, I would not try using this receptacle.
I offer my opinion as a starting point in your research. I'm not an electrician!
Best of Luck,
