Help with sign language (ASL)?

I do not know the song but lking at the wrds I wkd go with the idea of having different machines...ie sign Ie one like an old fashioned hand cranked mixer, one like another machine. Seems the point of the song is they have tons of unneeded machines etc. Take the funniness in the lyrics (gizmo, thingamajig) and match them w funnyish looking signs using clifiers.
