How to make a small crossbow out of common hosehold items

So I saw this on my Google homepage today, and since I'm behind in blogs, thought id post it. Enjoy.

Steps
1. Line up two of the pencils parallel to each other and secure them with tape, leaving at least a centimeter untaped at both ends in order to leave a space for the rubber band later. Repeat for the other two pencils.

2. Create a cross that looks like a lowercase "t" with the two pairs of pencils. Secure them in that position with either tape (electric tape works best), rubber bands, or glue.

3. Unscrew the tip of a cheap or useless pen. Unscrew the other side of the pen, and then take out all of the inner mechanisms. (Save the ink cartridge because that will be used as the ammo later.) After doing that, you should end up with a hollow tube.

4. Secure the tube to the vertical side of the cross with tape.

5. Stretch a rubber band horizontally across the crossbow, anchoring it between the two pencils and going over the pen in the middle.

6. Wrap a piece of tape around the middle of the rubber band where it passes over the pen.

7. Tie a rubber band between the pencils and the bottom of the hollow pen. This is to add elevation, which will come in handy later.

8. Put the ink cartridge back into the tube so that it's sticking out slightly.

9. Stretch the rubber-band to the end of the tube.

10. Grab the ink cartridge, pull it back further with the rubber band, and let go.
