Gangnam Style by PSY has the highest number of views of any YouTube video. Ever.
So many views, in fact, that Google had to rewrite the code for the YouTube counter!
Whilst they rewrote the code they also put in a fun little 'doohickey' that spins the number like a one-armed bandit.
So Gangnam Style now has..... wait for it.... 2,151,949,101 views.
Yes. 2 BILLION views and counting.
That is literally phone number numbers where I come from.
Here is the video in case you want to go and check it out yourself;
