Number 5 is featured in the backstreet boys hit "I Want It That Way" and if someone yells "NOW NUMBER 5" you are required to say "I never want to hear you say, I want it that way"

"NOW NUMBER 5" "I never want to hear you say" "I want it that way"

Possibly one of the greatest lines ever said. Yup. That's the one. This phrase killed my brother.

"Now number 5."
"I NEVER WANNA HEAR YOU SAAAAAAAY." *deep inhale* "I WANT IT THAAAAAAAT WAY."
