Tennis uses multiples of 15, but only up to 45, calls other points weird names, then closes a set, which has to be repeated at least 6 times for a separate scoring, with said scoring also needing to be repeated AT LEAST 3 more times, but can be dragged out ad infinitum.
Even table tennis has the decency of using a straight scoring system where 11 points wins a set and 2 sets wins the match.
They also replace the 0 with the word love. When the score is 15-0, the announcer says 15 - love.
