Think about it. We use the French expression "double entendre," meaning it has two definitions.@Zombie_61
I don't get it.
The joke is in Pulaski's use of the word "see" in her reply to Riker, which in this context has two definitions. "...I can't see him right now...", meaning she's busy and doesn't have time to examine him, and also meaning she would not be able to see him because he was actually invisible.@Zombie_61
I don't get it.
And that "Dad joke" humor was one of the reasons I've never cared for any of the Star Trek shows from the Next Generation era--swing and a miss on the "humor" and the "action", and very little of it believable even as science fiction; just a bunch of adults doing low level cosplay with few exceptions.When it has to be explained, it loses it's humorous intent. Too bad. I saw it first as a DAD joke. I thought it funny enough without the pictures.
