Ghost Busted

This is it! We're close to proving bakery hauntings, I can feel it!

Scoff all you like, but I was present at an undersea, unexplained mass sponge migration.

Not to mention they were wearing PANTS.

Look! Actual ectoplasmic residue! This is great!

"He slimed me."

Oh buck up, Frosty, you'll be fine.

Talk about telekinetic activity - look at this mess!

It's like the Salem mass Silly String turbulence of 1947. DEFINITELY supernatural origin.

You know, I collect spores, mold, and fungus...

...but that is just NASTY.

Listen! You smell something?

"There is no 'wee wee,' only stool."

Hm. You'd better get a sample.

What, you question my methods?

Back off, man; I'm a SCIENTIST.

That's better.

Oh, and whatever you do, don't cross the streams. That would be bad.

I can see you're still not convinced on this bakery ghost thing.

Then answer me this: would any human being stack cakes this way?

I rest my case.

Thanks to Anna S., Matthew Z., Alyssa P., Dylan W., Lindsey D., Cynthia C., & Anna A., who are pretty sure that sample cup means "you're in trouble."
