This is a longrunning thing, but the way that sign at Richmond + John says "FUN IS PARAMOUNT", yet the "N" is in a yellow so faint, it reads as "FU IS PARAMOUNT".
Reminds me of that old MAD thing on burnt-out neon signs, like "IVORY SOAP 99 44/100 PU[re] ", or "YOU CAN [be] SU[r]E IF IT"S WESTINGHOUSE"
