Throughout the past three decades, "Star Trek: Deep Space Nine" enthusiasts have shown an almost surprising amount of affection for the bristly, business-oriented Quark.

Quark has several notable features, including a bulbous forehead, a protruding brow, and impressive ears that can hear the quiet footsteps of a Rafalian mouse outside his quarters.

When "Deep Space Nine" was still airing, actor Armin Shimerman showed the physical differences between himself and Quark during an interview on "Live with Regis and Kathie Lee."

According to the actor, putting on the makeup was a three-hour process, and the top half of his face was covered with a helmet that included Quark's iconic ears.

Shimerman also revealed the secret behind Quark's pointy, jagged teeth. "They just pop on. ... Fixodent, Poligrip — they work. Those products work!" said the actor.

He appreciated that his natural appearance was nothing like the Ferengi, saying he was not approached by fans when he attended conventions in his regular attire.

"I walked around for 45 minutes. People didn't look twice. I had all the anonymity in the world," Shimerman said.
