There was a commotion somewhere toward the back of the crowd. People were swearing or yelling indignantly as they were being roughly shoved aside. Reese-look-alike's head snapped in that direction. I turned to look also.

Arnold Schwarzenegger was moving with determined precision through the milling crowd. Straight toward us. Wearing black shades, a leather jacket, and tight biker jeans.

"Oh man, you have got to be kidding me..."

"Run!" Reese-look-alike shouted. He jerked me forward into a run. I kept glancing back. Arnie was having trouble pushing his way through the crowd, as people were rushing up to get their autographs signed.

"Look, Reese, or whoever you really are," I panted, trying to keep up with him. If I didn't, he'd just end up dragging me along anyway. I didn't want that - not very dignified. "I don't know who put you up to this elaborate scheme. I mean, April Fool's is still ages away, but I get the picture, okay? Very nice touch with the whole Arnie-Terminator costume."

He just stared hard at me, then pushed me onto the ascending escalator.

"Ok, so your Reese's grey overcoat costume's pretty realistic too. But can we just cut it out now? I've got to-"

There was a deafening explosion. Behind us, people screamed and started running like wild elephants. "What the..." I turned, frowning.

Arnie had had enough. In his muscular arms was a gigantic UZI submachine gun. And it was pointed straight at me.

"No fricken way..." I began.
