I am in a gas chamber! Someone keeps farting and is really stinking up the office! I have two suspects, both pretend like they have no idea what I am so upset about. And no, it wasn't me, I can't fart after I had the surgery...
Lets take a look at the evidence...
And here is Stan, napping under his usual blanket (well, at least you see one of his paws sticking out...)
So who dunnit???
It was Bob!
And how do I know that? Well, first of all, Stan is all wrapped up in a blanket, so much harder for any stink to leak out, and second of all, did you see the clue???
Mystery solved, now I just need to open a window to clear the air!
