(Anyone get that reference?)
Did you mean LSD? Or are you referring to the Latter-Day Saints, which may cause people to write entries into the Hall of Shame?
I think he is referring to one of the early Star Trek movies, where Kirk uses this malapropism in an attempt to cover for the disguised Spock's Vulcan identity and his perceived strangeness while visiting an historic planet Earth. Did I get you, Chairman?
