When Johnny, after failing several times to get Ben to slap himself in the face with the hand covered in shaving cream, finally succeeds.
What's even funnier is the music in the background and how Johnny throws his hands up in the air and his expression of success.
The scene when the gang is watching Johnny on TV at the Moto-X Games.
Reporter: So, what are your superhero names?
Johnny: They call me the Human Torch. Ladies call me Torch.
Reporter: What about the rest of the team?
Johnny: (shows a picture of Sue) That's the Invisible Girl.
Reporter: What about your leader, Reed Richards? I hear you call him Mr. Fantastic.
Ben: Could've been worse.
Reed: I guess.
Reed does get a little upset about Johnny's next comment.
X Games Reporter: Is it true what they say about him? That he can expand *any* part of his anatomy?
Johnny: Well, I've always found him to be a little limp.
Ben enters the lobby and bumps into Johnny.
Johnny: Hey! Look what the marketing guys did! Look, check it out, listen, listen, you'll love this... (holds up a little Thing doll that says, "It's clobberin' time!" in a squeaky voice)
Johnny: It's catchy, right?
Sorry, Johnny, but Ben doesn't agree with your assessment.
And Johnny's reaction to Ben's crushing of it:
(whining) Awww, that was the prototype!
The typical reaction of most people when they see Ben for the first time after he becomes the Thing.
When Ben wakes up in hospital after the incident at the Space Station, Johnny is there, telling him that "everyone else" is fine, that the doctors and plastic surgeons did "everything humanly possible". The audience think that he's become The Thing, but it turns out to be just a prank by Johnny when Ben actually sees his reflection. Crosses the Line Twice, but still.
Johnny: Unfortunately, the doctors just couldn't do anything to fix your face.
Rise of the Silver Surfer
A much needed Mood Whiplash after Doom jacks Silver's board, kills the General, pwns the Four, and blows the joint:
Ben: (gets smashed into the wall by a large concrete slab) OK. That one hurt.
Susan: Where's Reed?
Reed: (muffled) Back here!
Ben: (steps out from the wall to reveal a flattened Reed) My bad.
After Doom shows the Four a video of the Silver Surfer
Ben: I liked the part where he knocks you on your ass.
Early in the film, the Four are forced to fly coach and Ben is wedged into a tiny seat. He looks out the window and sees Johnny flying beside the plane.
Ben: I hope it rains...
Before the wedding:
Alicia: Hey, Johnny. (turns head slightly in his direction)
Johnny: (taken aback) Wow. Does that always amaze anyone else? How did she know it was me? I didn't say anything!
Alicia: Well, to be honest, you kind of smell like ash.
