Lol, how'd you know? One time I went into Rochester Big & Tall and they told me I had the largest neck they'd ever seen. That surprised me a little and that's when I quit working my neck. Ah, the good old days! I'd give my right arm to go back. I feel like I was just getting started. :-(
When you have to cut the neck out of a V-neckline...you've gone too far.
When a neck tie ends up 3 inches long after knotting..you've gone too far.
When your neck size is larger than arm length ...you've gone too far.
If you suddenly acquire the moniker "Bull" you've gone far enough..
