So, the Tate Modern has installed a giant crack in its main hall.

It's supposed to symbolise division in modern society. Personally, since it's already started to rack up victims, I think it's a good idea for a few laughs:

• Hang around the crack, and try to stealthily shove people in.
• Cover it up with sticks and leaves, to trap the unwary.
• Turn up with a cement mixer and start filling it in, citing health and safety concerns.

Well, that's just for starters.  If anyone's bothering to read this - how about a few more suggestions?
