I did a few times in 727s. No big deal, just make damn sure not to hit the brakes.
I was in the right seat one day and the guy in the left seat did hit the brakes, realised what he did the second he hit the brakes. We didn't go back on the tail skid, but it was close.
He was an experienced PIC as well, later he admitted he just had a brain fart. He did buy the beers that night.
