Psy created the dance of the year in Gangnam Style.  Anywhere you go, you see people doing the Gangnam Style horse dance.  But, the Korean popstar did consider other animals.  He discussed the song at Oxford University.  On the dance he said:

"I stayed up for 30 nights to find that horse-riding dance.  I tried every creature: elephant, monkey, kangaroo, snake. The kangaroo hopping was too slow, so we ended up imitating a horse."

The video has over 650 million views on Youtube.  If Psy could kangaroo hop faster, you would be doing that dance.
