Megatron, to two Autobots: Look, if either of you get across that sinkhole in front of you, you get the seeker.

Starscream: That's right, losers! You take one step and you're dead! *throws rock which bounces off the "sinkhole" instead of sinking*

Starscream: .....

Starscream: You were bluffing, huh?

Megatron: Yeah. Yeah, that was a bluff...
