It's not so far-fetched. George Foreman and Mr. T both have weird-ass branded products. Why not a Patrick Swayze microwave?
The jokers at Grocery Eats have mocked up what such an appliance might look like.
The power knob references Swayze's roles over the years, going from lowest to highest in terms of character badassitude—Vida (To Wong Foo ...; low power), Johnny (Dirty Dancing), Sam (Ghost), Dalton (Roadhouse), Bodhi (Point Break; high power).
What, no Jed Eckert?
Also, when it trips your circuit breaker, you can blame Jim Cunningham.
