"House on Possessed Hill":
(Joe's trying to talk Frank into investigating a supposedly cursed house)
Joe: Frank, you're not scared of going there at night, are you?
Frank: Yeah, that about captures the spirit of it.
Joe: Okay. Okay. I guess I can face the demons of the night alone. See you in the morning.
Frank: (after Joe walks away) ...brothers.
"Defection to Paradise": Harry Hammond has just tasked Frank & Joe with finding an expensive concert speaker stolen from the group Bread; Frank and Joe are driving in Hawaii, discussing how best to handle the case. What follows is one of the funniest moments in the series, with the brothers planning how to totally take advantage of Hammond & the US Government:
Joe: Now this is what I call an assignment. Hanging out in Hawaii for a couple weeks, checking out the local action...
Frank: Joe, we still have job to do. We got to find that missing speaker — you know how difficult that's going to be?
Joe: Yeah, yeah, I know what you're going to say. But stealing a series G transonic speaker is like stealing an aircraft carrier. I mean, the minute you take it out, you're in big trouble.
Frank: Kinda sticks out in a crowd.
Joe: Yeah. Besides, who would be stupid enough to steal a speaker, then take it out & show it off in front of everybody?
Frank: (obviously trying not to smile) You got a point there. I guess this could be a long, tough case, waiting around for whoever lifted the speaker to get enough courage to show up in public with it...
Joe: You got it. Now the way I see it...we spend our days with the surfing crowd —
(Frank gives Joe one of those knowing half-smiles)
Joe: — well...just to pick up any extra information.
Frank: And how do we spend our nights?
Joe: Force ourselves to stay up late. Hit all the big spots.
Frank: Yeah. Yeah! Constant vigil!
Joe: We don't the meaning of the word sleep. I think we owe it to our country.
Frank: (now smiling openly) Yeah...I can't argue with you. When you're right, you're right. We could be stuck here for several months.
