Radar / Shrek the Third

• The first scene with Shrek and Fiona in bed denotes something suggestive. It's implied that they had sex the night before, the reason they didn't appear in the intro. They wake up and clearly seem very pleased. This is probably when Shrek impregnated Fiona.
  • Bonus points for Donkey pulling back the bed covers and is clearly horrified that Shrek isn't wearing underwear.
  Donkey: AAHHH! You know, you really need to get yourself a pair of jammies!
• When Shrek hears that Fiona is pregnant, Puss tries to give him The Talk.
  Shrek: How did this happen?

  • One of the boys says, "For lo, bro! Don't burn all my frankincense and myrrh!" Not even sneaking past the radar.
• After Shrek finds out about Fiona's pregnancy Puss says
  Puss: And you, my friend, are royally (cut off by a foghorn)
• This exchange between Donkey and Puss In Boots after they've switched bodies.
  Donkey: [In Puss' body] I feel all exposed and nasty!
  • And this:
  Donkey: [trying to walk correctly in Puss' body] How in the Hans Christian Anderson am I supposed to parade around in these goofy boots!?
• After Shrek and Fiona put their children to bed Shrek asks "So what do we do now?" in a sly voice and they look suggestively at each other. Cut to a shot of them fully clothed and dead asleep.
• Shrek about Merlin: "If Artie trusts him, that's good enough for me. Even if his robe doesn't quite cover his—"
