Marco: Calm down, I'll see what I can do about finding your little toy. Captain Murphy: It's not a toy. It makes real cupcakes, with a 40 watt bulb, and there's icing packets. But the secret ingredient is love. Damn it. Marco: Just try to calm down, go have some pudding. Captain Murphy: Pudding can't fill the emptiness inside me! But it'll help.
Captain Murphy: You better find me that Happy Cake oven, or die trying. Hear that Stormy? Die.
Also in that same episode, Murphy has a picture of Debbie sleeping naked.
The Stinger in I, Robot where Harry Goz is asked to read Murphy's line "There go my nipples again" in various ways.

The entire exchange between Sparks, Stormy, and Hesh in "Green Fever" regarding their pipes.
Murphy: Oh now I remember. Quinn: Remember what?! Murphy: Well, you know how people rescue greyhounds from the tracks? Marco: Those weren't any greyhounds! Murphy: No I don't like greyhounds. Too pointy. So I rescued some fighting pitbulls from Guatemala. Quinn: What?! Murphy: Yep. Tough little bastards too. Sparks: What the hell were you thinking?! Murphy:(punches Sparks out cold) So I came here to the closet to get them some food. Marco: They haven't been feed in three days?! Murphy: Well, more like ten, because I keep forgetting. Debbie: We're trapped! Murphy: Yes, yes we are. But, it could be worse? Marco: How?! Debbie: This is as bad as it could get! Quinn: How... could it possible... get any freakin WORSE?! Murphy: We could be out there... like Stormy. [Gilligan Cut to Stormy running from the pitbulls]

Bizzaro in general - the overall plot is the sealab crew is held hostage by bizzaro versions of themselves.
Quinn: Why did you let them on board in the first place ?
Murphy: At first they seemed nice...
And the Bizzaros cant decide what they want from the crew - a destructo beam and diamonds (both of which are non existent).
Debbie: I thought you wanted the destructo beam.
Bizarro Murphy:...Now we want both.
Eventually they introduce Bizzaro Quinn; an alien like creature (who Murphy nicknamed turtle face) that hatched from an egg and spends half of the episode bouncing around saying "Bizzaro", beofore it ends up attacking Bizzaro Sparks (who's a floating head in a jar).
Bizzaro Sparks: Put me down! PUT ME DOWN!
Bizzaro Quinn: We're friends!
(Bizzaro Quinn smashes Bizzaro Sparks to the ground breaking his jar.)
Bizzaro Quinn tries helping Bizzaro Sparks by pouring salt on him.
