Keeping with my belief that Tenzin is a superhero, Rachel and I recently discovered his kryptonite...our son's only weakness appears to be fake sneezing. Upon hearing a fake sneeze, Tenzin starts giggling uncontrollably. Said giggling will intensify with increased fake sneezing. If giggles get loud enough, possible toots may occur. There is no guarantee that those toots might be dry.
Enjoy [please disregard Rachel's orthodontics at the end...we'll save the tooth video for next time].
