As far as examples go, here are some of mine:
- Edward- Lock him in a room with Wrath after an "all-you-can-eat" buffet consisting of mounds of sugary goods and cappuccino.
- Riza- Deliver a giant cake to her and, when she takes a bite, have Roy pop out wearing a miniskirt.
- Envy- Dress him up and put him in a compleatly different anime. Afterwards, yell at him for being in the wrong show.
