CORRECT! A metal one
A Dildo ?
All are correct. Sorta. Steely Dan is a William Burroughs reference from the book Naked Lunch. Steely Dan is a strap-on rubber penis - it is not metal. Check out this excerpt from Naked Lunch
Becker and Fagan are too clever by half. Several of the their songs have overtly homosexual themes, e.g., "Rikki Don't Lose that Number," "Gaucho" etc. I try to ignore the more flaming lyrics and ranchy allusions and concentrate on the music--which is absolutely first class. But it is Fagan's solo effort "The Nightfly" that is my favorite SD-flavored CD.
