So, either it's not fun at all, or this person is convinced that "funnest" isn't a word but couldn't be bothered to write "most fun" instead. Thanks, Kristy.
I'll let submitter Scott explain this one: "This sign is posted at a dog training facility. It does actually mean treats that people give their dogs during training, but the quotes make me wonder whether it's also a euphemism for, um, doggie calling cards."
I imagine a behind-the-scenes for this one when somebody is about to print up the sign and the office nit-picker points out that it's not REALLY free because SOMEBODY pays for it. Rather than argue it, the sign-maker just puts the quotation marks there and hangs it up. Thanks, Jack.
As the photo demonstrates, the dryer here is really missing glass. I guess the quotation marks are to clarify that there is still glass in the world. Thanks, Bruce.
