Star Trek fans who have wondered what it would be like to wear an actual captain's uniform may now have the opportunity to answer that question.

The easy part is entering. First, Star Trek: Enterprise viewers can vote online at upn.com to pick their favorite episode from the past four seasons and then, separately, enter to win either the Grand Prize, a genuine Captain Archer Starfleet uniform, or be one of 25 to win the first season of the show on DVD. The three episodes receiving the most votes will be broadcast in ascending order on Friday, March 25, Friday, April 1 and Friday, April 8, all at 8:00-9:00 p.m., ET/PT on UPN.

For those participating, you can watch video clips from the following 10 Enterprise episodes that have been handpicked by the executive producers:

Season One
"The Andorian Incident" — The Enterprise crew pays a friendly visit to an ancient Vulcan sanctuary, which has been seized by paranoid, combative Andorians.

"Dear Doctor" — The Enterprise crew encounters an alien race in desperate need of medical assistance, but Dr. Phlox refuses to help them because of his ethical beliefs.

"Shuttlepod One" — On a routine shuttlepod mission to investigate an asteroid field, Trip and Reed find themselves cut off from Enterprise and become convinced that it's been destroyed.

Season Two
"Dead Stop" — After docking with a mysterious, automated space station that inexplicably fixes everything, the Enterprise crew searches the unmanned station and discovers its unique and horrifying power source.

"Cogenitor" — The Enterprise crew encounters the Vissian, whose mating rituals require three genders to procreate. When Trip discovers that the "third gender" suffers from extreme discrimination, he takes matters into his own hands.

Season Three
"Twilight" — After an accident, Archer loses his short-term memory and wakes up 12 years later to find that Enterprise's mission has failed — the Xindi have destroyed Earth and are hunting for the remnants of humanity.

"Similitude" — After an engineering room accident leaves Trip severely injured, Dr. Phlox attempts to save the chief engineer by creating a clone named Sim-Trip, who surprises the crew with his accelerated growth and detailed memories of the real Trip's life.
