Seems like this “Friday” craze will never end! Even Katy Perry is singing it at her concert in Melbourne on (what day?) Friday, April 29.

I guess Katy probably just didn’t get enough of teaching little kids after the “Hot and Cold” cover with Elmo. Now she’s even teaching kids about the days of the week. However, I have to say that Katy’s cover is a lot more tolerable than the original.

What do you think about the cover? Does Katy do it better?
