You do have a point but still let's look at it another way.

It's a ticket. That means that at best it's boring and mundane. The writer knows this and is trying to convince you, to sell you, on spending some time thinking about it. Granted, you should do that anyways but First test new features before sending to customer doesn't really convince you to do that. If your text was enough then maybe it should have been a check box and saved everyone some time.

All that said, there is a time and place for humor. Maybe this was it and maybe it wasn't. Dunno. Audience matters; timing matters; context matters.
