Do I Go For The Joke Or Not

I saw this when riding the bus recently.

Clearly, this is a makeshift bar to indicate that the back door is broken and I should not use it. However, should I go for the joke that I mistook it instead for a race finish ribbon and just run through it? I’d certainly get in trouble, and run into the back door since that wouldn’t open. Would I do it anyway so as not to waste the joke I thought of?

I think this is more fun if I don’t tell you which way I decided.
