Planet 51/Radar

There seems to be a lot of dirty jokes that go just a little over the kids' heads in this movie...
 * In the beginning, when Skiff is warning Lem of the upcoming alien invasion, he states that he already "has protection against the alien's favorite form of analyzation- the probe". He gives Lem a cork and gestures, ahem, where to put it, to which Lem responds with "Yeah, yeah, I get it" before he can say the word itself. Then he says, "Oh wait, I already used that one!", and Lem's reaction? Pretty much shock and disgust and he drops the cork immediately. Really, that entire scene is pretty much made out of this.
 * When Neera comes out of her house, and Lem is prepared to make his move, his father tells him: "Go on, soldier, take that hill!" and chuckles.
 * A police officer watches a woman walk by, particularly her chest, and the woman tells him to "Keep his eyes on the aliens."
 * When Skiff bursts in on Chuck teaching Lem to woo girls, they look as though they are about to kiss and Skiff shouts: "The cork! The cork!"
 * Near the end when a blanket falls off a naked Chuck as he stands up, Skiff remarks "That's an odd place for his antennae."
 * When Chuck first introduces himself to Lem, Lem extends the S while attempting to say "Astronaut". Chuck's reaction makes it clear that this is intentional.
 * "Okay, either your name is Lem, or you want to mate with me".
