does anyone know which spongebob episode this is?

i can't remember most of the plot of it, but spongebob is trying to rescue someone (or something) and he says something like "i can't just let him stay there! he'll never know anything about what life is really like!" and then the show goes to a clip where there's a fish and it shows him getting up in the morning, sitting in an office at his work, and then standing at a window at his house, then his wife says, "are you coming to bed, honey?" and the fish guy says, "yes, dear." does anyone have the most remote idea of what the plot is in this episode, or maybe even know what the episode is called? thanks!

ps- i've already tried youtube, but with the little detail i have to search with nothing comes up....
