Katy Perry is not only a great entertainer, but a good sport.

When she invited an enthusiastic fan on stage in Rio, she got more than she bargained for. The fan got so excited she started kissing Perry, and licking her. Katy soon realized that the fan was high, which she called 'rolling.'

It gets funnier, yes that's possible. Katy tries to get Rayane, who pronounces her name 'ayayay-ah' to teach her Portuguese. Watch and laugh. I was rolling with laughter, myself.
