In some of the most popular NBA commericals lately I have seen some sentences and wondered if they were gramatically correct. In the NBA commericals "where amazing happens" they replace the word "amazing" with other words as seen here.. YouTube - NBA Where Amazing Happens Houston Rockets
. The two sentences i'm questioning are : "where streetlegends happens." and "where champions happens." Are these gramatically correct? Should the "happens" be pluralized?
Where street legends happens
Where champions happens
The template is Where <something/it> happens.
