A wall

crap...

A cardboard box.

Commence hiding.

A meat mallet. It could be worse, I guess...

A pocket dictionary. I'm doomed...

A gigantic plywood android phone.
Sweet! I can call the gigantic plywood SWAT team.

*Metal gear solid music*

2 students and 1 teacher (I'm in school on my phone)

Use them as bait so I can escape.

The TARDIS. I'd run inside, say "It's bigger on the inside", and go back in time (to the roman empire or ancient China).

A bookcase filled with books.

Bash the zombies in the head with them, and then tip the bookcase on them when I run out of books.

A MacBook

Ima die

An eggnog milkshake.

No creature, alive or undead, can resist them, so I'd be okay.
