Does anyone else remember a TV commercial (probably for shoes) that ended with someone tying a shoelace this way (or very similar)? I learned it from that commercial, but I forgot what it was advertising so I could never find it again.

(ETA I just slip my foot in and out of shoes without having to tie/untie them at all, saving even more time than this knot. This is known as the Hannifin Slip and I'm the inventor.)
