Symbols found in the moveEdit
When Bill and Ted are playing Death in Battleship, they yell "J7," sinking Death's battleship and winning the game. The number 7 is connected to God and all things holy in the Bible. Later in the film, J=10 plus 7 equals 17 which is also another number of interest, specifically relating to the death (and eventual resurrection) of Osiris. Ted is sitting next to a fuzzy dice arrangement in the car which to seven. The friends live in apartment number 33, and Keanu throws up three fingers twice shortly after the 33 door is in view.
