请检查以下文章中可能存在的语法错误： 
“Their were to many people in line for the bathroom. It was a crazy seen!”
There are two errors in this sentence:
1. "Their" should be "There" because it is used to indicate the existence of something.
2. "To" should be "Too" as it means excessive or more than necessary.

Corrected sentence: There were too many people in line for the bathroom. It was a crazy scene!
