Kirk Vs Kirk
by Ambassador T'Raen
Kirk and Alternate Kirk finally meet. Though all doesn't go as was planned. They engage in a battle of the wits! Who do you think won the battle? R&R please! Humor, uplifting if in a bad mood or just want something kinda funny to ready. I wanted more references, though I dialed down on the many I was going to use! K For some moderate language.
