I have seen some air conditioners that do have them. I would guess the idea is to make use of existing outlets that are 120 volt 20 amp, rather that the disadvantage to many people of wiring a new circuit.
While searching for UPSes in the 1-3 kVA range, I've seen some with such a plug specified.
I'd rather go with 240 volts in these cases and have the circuit brought in. If I was putting an A/C in where one previously had a dedicated circuit, I'd go with 240 volts and convert the circuit if needed.

I've never actually seen such a patch job, and certainly would never recommend it. But in DIY type forums, I've seen a number of people ask how to do it (IMHO, that would not be a project for someone with so little experience in wiring they would have to ask how to).
| Must of this thread has been quite silly and pointless.
Most threads seem quite silly and pointless to me when discussing something that I don't happen to need. This particular thread certainly has gone off on a tangent (both in subject and in plug blades). But it has shaken up some dust that probably shouldn't be where it has settled long ago. I am considering making an information web page on the subject "15 vs 20 amps".
