The Ultimate Redshirt (S1E12)

When Captain Picard has a big linguistics test to study for, he decides to procrastinate in the holodeck instead. Disappointing everyone, he chooses a program about a 1940's-era private detective, so Data, Dr. Crusher, and a random crew member join him. Turns out, there's a malfunction and people in the holodeck aren't shooting blanks anymore, which would be a real problem if Picard had been able to get Beverly up on his desk like he wanted to. Will the Enterprise ever fix the door problem? What does holodeck gum even taste like? It's the episode where we give everyone a little dusting of Drunk Shimoda.
