GridWord #385: Fortune 500

djr={gridby, dart, axoq, ringer}

In honour of everyone's favourite mathematics-based fortnightly not-printed-on-newsprint publication producing its 500th issue, I have returned from post-graduation obscurity to bring you one last Gridword. May the gods have mercy on your souls.

As was the case for all of my Gridwords, the cryptic crossword and conventional crossword have identical grids. Since I am three parts bonkers something strange is happening in the conventional grid, making it an unconventional crossword. In this case, two symbols have been incorporated into the grid, each of which replaces a word which appears numerous times in the entries. For example, if I chose STICK and STONE as my two words to replace, "joystick" would only take up four squares, the last of which would have a drawing of a stick, say. "Pull a fast one" would similarly be eight squares long.
