Your choices were the following:

• (a) Greet them at the door with a warm hug.
• (b) Lock the door and not let them in.
• (c) Pour ketchup on yourself and lay in the middle of the kitchen floor.
• (d) Park the car around the corner, hide in the bushes, leave a note on the door saying, "I hate you, and I'm never coming back," and then when they start to cry, jump out of the bushes and say, "Booga booga booga!"

This one should be a no-brainer. (a) is obviously wrong. (b) is a good start, as is (c). (d) is a masterpiece, however. It causes pain, it's unexpected, it's an untruth, and it's wordplay because "booga" is not technically an English word.
