Dirty little trick

See that chair there? Looks comfy, doesn't it? That's what I thought too.....

Until I sat down and found my bum resting on the cement. Someone played a trick on me.
The culprit?

I have three guesses: One of these two.....
This one.....
or this one.....
I'll do some further investigating and let you know what I find out.

For now, safely on a wooden chair,
