I still can't remember how to do one on demand. I always have to pull out a how-to guide video and then fail at it about 4-5 times before it's the least-bastardized version of the knot.
Okay then, know it all, are you sure? Which knot configuration is it? Are you sure it's not cheating with starch or an insert? I've seen the same bowtie tied differently and looking completely different.
So I point to their shoe and say, "The open secret is that it's the same knot."
