As editors of HuffPost Parents, we consider ourselves experts in the parent blogosphere. But even we were confused when Billy Eichner asked a "Billy on the Street" game show contestant to identify certain phrases as either a Train song or a mommy blog.

"Drops of Jupiter"? That one was easy. "Souls Never Wrinkle"? We weren't so sure. (As it turns out, it's a lovely blog by a special needs mom named Janee.)

Watch the video above and see if you can tell the difference between Train hits and mommy blogs. It's harder than you might think.

This segment will air during tonight's episode of "Billy on the Street" at 10/9c on Fuse.
