Dallas native Roger Kaiser, identified as the guy who sprinkled a mentor’s cremains in the pit of the Met yesterday (and all that came after) is a parterre commenter, or rather was a parterre commenter, submitting over 800 comments between 2007 and 2009. La Cieca will respect his anonymity on parterre.com and not disclose his screen name, but she will just note that his comments were no nuttier than most. (Photo: Facebook)
