SWA taxi legends are not quite as true as they were before, but occasionally controllers kind of lean on that kind of forward-leaning attitude to get the job done. My last departure out of DEN, GND mentioned something about getting to the runway before it shut down for an inspection or something. Nobody got scared, nothing got broken, but we did manage to take off prior to the runway closure.

Rumors of hover-taxi in ground effect are of course completely groundless as far as anyone can prove.
