Speaking as someone with a few peircings I can only echo the sentiment of a comment left on Boing Boing:
"Nasty! Ok, I have maybe 120 hours of tattooing and at one time or another several extra holes, but I have never eaten with my mouth open in public; and that is what this is ALL THE TIME eating with your mouth open.
P.S. say goodbye to those gums in a few years,(abrasion)."
