I guess I'll hafta go back to the drawing board! How do I convince the Missus that I gotta bring another piece of Junque (oops, good stuff) into the house?
Actually you are going about this all worng. You need to convince her that you really need a rotisserie kit for your grill for cooking - lets say chicken.

Once you get it: cook a chicken FIRST and then feel free to apply the motor to "other" purposes which "enhances" the value of the appliance.

Of course after you try you will notice that you use it on your grill far more often than for "drying" stuff. Yummy.
