Enterprise (TV): The Ferengi are about to make their first appearance in the Trek timeline according to TrekToday. The upcoming episode "Acquiusition" has four Ferengi pirates managing to render the entire crew of the Enterprise unconscious in order to board and search it for - what else, items of profit. Tucker however is in the decon chamber (no doubt showing offhis undies again) when they board the ship, and avoids inhaling the gas used by the Ferengi to infect the atmosphere - he wakes up Archer and T'Pol, and the three begin to work to take the ship back. In order to fit into continuity, the crew will never learn the intruders were called Ferengi thus leaving the way for the official 'first contact' two centuries later in "The Next Generation" episode "The Last Outpost".
