George rescuing the skydiver caught in the bridge.
Ursula's mother, who refuses to let her be with George, is aghast when Ursula realizes she loves him and wants to go the jungle to find him. She looks to her husband and snaps "say something!" Her husband just smiles and says "Be careful out there, honey."
George performing the "biggest swing in jungle history", crashing into a tree so hard it cracks in two. And this time he does it on purpose, to save Ursula.
The montage of George marathon-running back through the African landscape to save Ape, coupled with Awesome Music.
