A cartoon frog gets splashed two times: Once by falling down from height, and once by swallowing a grenade.

Some cartoon characters get electrocuted, and become live-action humans.

Two men slap and fight each other in a rather comical matter.

Two characters get caught and tied in rope by several people.
