I had forgotten that Star Trek actor Armin Shimerman, best known for playing Ferengi bartender Quark in Star Trek: Deep Space Nine, also made an incredibly weird appearance in Star Trek: The Next Generationseason 1. Because the Star Trek franchise has been going for almost 60 years, you'll often find familiar Star Trek actors in minor roles before becoming iconic characters. This is especially true for actors like Shimerman, who are not only versatile character actors, but also able to tolerate long days in heavy makeup, as Star Trek so often demands.
