Fischer Price Strings
These are some of the worst strings I've ever tried. The basses sound adequate but certainly nothing special, with the A string having noticeable intonation issues, sharp at the 12th fret. The nylon G string was the worst of the set, being intonation-sharp beyond playability. The B string was bad as well, but not nearly as sharp as the G. I left these strings on the guitar for 4 days just to see if they would settle in, and ended up taking them off when it became clear that they were not worth fighting.
