Sheldon and Amy's wacky relationship and Howard's aversion to worms and gutting fish took the spotlight in "The Fish Guts Displacement." 

With the exception of the opening montage, Sheldon was off on his own being a good boyfriend to Amy, while the others attempted to help Howard prepare for a fishing trip. The lack of connection between the two situations was noticeable, but overall the episode was funny. Though, a few moments out-shined the rest.

Sheldon's sudden uneasiness over the Spider-Man theme song was typical Sheldon, which also means it was hilarious. When he broke out singing the theme songs, I cracked up. For a man of his intelligence, it's amazing what he comes up with. Here's the exchange:

Sheldon: Is anyone else troubled by the Spider-Man theme song?
Leonard: Why would it trouble you? It's like your third favorite cartoon theme song.
Sheldon: It is, right behind [Sheldon sings "Inspector Gadget" and "Teenage Mutant Ninja Turtles" theme songs]
Sheldon: However, the Spider-Man lyrics posit that Spider-Man's Spider-Man does whatever a spider can.
Howard: Yeah, so?
Sheldon: I can think of many things that Spider-Man can't do that a spider can. One crawl in your ear and die, two legally leave Guatemala without a passport, and three have sex with a spider. | permalink

Seriously, sex with a spider? Maybe Sheldon does know something about sex after all. While he is a high level thinker, Amy got him with her "extended" sickness. Though, I have to give him some credit, he did eventually catch on. "Liar liar pants on fire," anyone?

While Sheldon has started demonstrating his affection (love?) for Amy, she has learned how to manipulate him into any physical contact she can get. Vaporub?

Sheldon: No. I need to get you down for a nap. For some reason that Vaporub gets you all fired up. | permalink  

Amy kept her sickness thing going to keep her love close. Though, her "help" in choosing the punishment for lying perhaps was even more epic. Spanking?

Amy: Are you saying you want to spank me?
Sheldon: I don't want to. But, it looks like you have left me no choice.
Amy: That's true. I've been a very bad girl. | permalink

Each of their interactions was hilarious. As much as I'd love to see Sheldon just give in, pull her into a kiss and seduce her, I'd miss the humor from their awkward relationship.

It's intriguing how sometimes awkward works, while other times it doesn't. Howard's visit to Bernadette's parents was not very funny. If anything, I felt terribly uncomfortable for Howard. Though, as a set-up it succeeded. 

For a group of men, it's telling that the manliest of their friends is also the most feminine of the group -- Penny. Howard's interactions with the worm and fish were ridiculously amusing. First, he put the worm over the hook? Seriously? "Jam a hook into his face!" He did do better pulling out the fish innards ... until Penny's comment about the eggs. Those guys are super queasy! I shouldn't talk, though, I can and have hooked worms, but gutting a fish, no thank you!

The lesson was good for all of them. It was nice to see Penny be able to show off her knowledge about something. So often, it's her doing the learning, so the change of pace was appreciated and provided for some good fodder.

Howard should feel much more at home at a casino table, then he would out fishing or hunting. The men's bonding over their wives at the end was a nice conclusion.

Howard: Boy, we're married to a couple of ball busters, huh, Mike?
Bernadette's Dad: That's my wife and daughter you're talking about.
Howard: Great couple of gals.
Bernadette's Dad: I wouldn't go that far. | permalink

While they may not talk much, they definitely have something in common with their wives.

Overall, the only scene that didn't really work for me was dinner at the parents. The episode has some great one-liners, as well as, extended funny scenes. For more of the best lines, check out The Big Bang Theory quotes section.

What scene did you find the funniest? Did you enjoy Amy's antics? Or, Howard's cheerleaders?
