-WTF! That guy just did a backflip, played the flute and peed his name in the snow all at the same time! I don't even know what word to describe that with.

-Well, was it fantastic?

-Yeah.

-Was it wonderful?

-Pretty much.

-Would you say there may be magic involved?

-Sure.

-Then it was fantasmagicalderful.
