What if :

Rihanna, Eminem and The Ting Tings singing together, it would be like :

Rihanna           : "Oh nana, what's my name..oh nana what's my name..what's my name?"
Eminem           : "My name is? My name is?"
The Ting Tings : "That's not my name..that's not my name..that's not my name"

It's all about name, my friend. They all forgot their names. Haha. Just saying ;)
