For most, Klingon as a second language (KSL) is probably sufficiently nerdy. But not for this dude...
Meet d'Armond Speers, a man who spoke to his infant son ONLY in Klingon for the first three years of his existence. According to Mr. Speers, he's not even a huge Star Trek fan, he just wanted to see what would happen:
"I was interested in the question of whether my son, going through his first language acquisition process, would acquire it like any human language," Speers told the Minnesota Daily. "He was definitely starting to learn it."
Well, that's good. At 3, the poor kid was starting to learn Klingon. With any luck, Worf Jr. be fluent by kindergarten, just in time for schoolyard ass beatings.
