Best sexy voice I ever heard was an Air France femme fatale in (if memory serves) a BA46. Once I'd controlled my drooling enough to issue a clearance and taxi, I asked if she needed the full length. An alluring "affirmative" came back, and I transferred her to tower having anotated "F/L" on the strip.
She lined up at the intersection and took off, so I turned to the tower guy and said "I guess she only wanted me giving her the full length...."
