Marvin, engaged in a titanic struggle with Bugs the White (formerly known as Bugs the Grey) at the gates of Minas Tirith, waits as the last inch of fuse on his Acme Destruct-O-Gate burns.
Unbeknownst to Marvin, however, Bugs the White has already slipped the REAL Destruct-O-Gate through a chink in the rear of Marvin's force field, when Marvin had his back turned, and put a plain old Fourth of July-variety firecracker in its place against the gate.
The fuse before the gate burns out. There is a mere "pop" as the firecracker explodes.
Marvin: "Where's the kaboom?! There was supposed to be a gate-shattering kaboom!!"
[Marvin himself is immediately engulfed in a large explosion which reduces him to a small pile of smoking ash. But the ash soon re-assembles itself into a somewhat charred Marvin.
Marvin: "You have made me SO angry!!"
