Especially for a piece of trivia like that. There's more flexibility about it when a show re-airs, and it's generally considered acceptable to bump its recap thread with a new reply--but only if you have something relevant and thought-provoking to say. This post fails both of those as far as I'm concerned.
But first things first: Squall, you said you "don't see it posted anywhere," referring to the tape date. The tape date of this episode is at the very top of the recap that was posted, so either you didn't read the recap thoroughly enough or simply missed it.
That said, Kitch has a tape date listed of 31 January 2011, not 1 February. If you feel like his information is in error, fine, but I'd suggest you at least cite a source if you want to try and get him to change it.
