Klingons may be "foul-smelling barbarians," but they sure know how to make coffee. The Klingon coffee known as raktajino became a staple on the Enterprise during the time of Star Trek: Deep Space Nine and Star Trek: Voyager. Captain Sisko was particularly addicted to the highly-caffeinated raktajino.
John DiMarco (previously at Neatorama) made a supercut of Starfleet personnel ordering or discussing raktajino over the course of several seasons. It will leave you craving a cuppa Klingon coffee, or else give you the caffeine jitters. I particularly enjoyed the sequence that involved time travel, as Odo and his DS9 companions encounter Klingons they do not recognize because they are made up in the low-budget Star Trek: The Original Series fashion. That's the kind of touch that makes us love Star Trek so much. By the way, those iconic cups they are drinking out of are available from many vendors online. -via Geeks Are Sexy
