Rhett and Link went from making commercials on YouTube to becoming stars of their own cable show, IFC’s Commercial Kings. Now the dynamic duo are back with another Caption Fail video.

Then they took the captions YouTube offered, which is still very error prone, and used them as new lyrics. The results are funnier than expected.
