This should've been called...
"What's Your Number?" because he was trying to get her phone number all night. At no point did he take her home.

Funny, you should say that because Anna Faris starred in a movie called "What's Your Number?" that was released only a few months after "Take Me Home Tonight" was released in 2011.
Maybe, the producers got the inspiration for the title "What's Your Number?" after watching "Take Me Home Tonight"?
