User blog comment:Fametown/The Most Popular ERBs to the Internet/@comment-26136579-20150621070732

Explanations for the Top 3:

1. Goku vs Superman: Common internet rivalry. Death battle video. Plus it's already a very popular ERB.

2. Darth Vader vs Hitler: It probably gets points every time Darth Vader 2 or Darth Vader 3 is mentioned or shared.

3. Obama vs Romney: Pretty obvious. People talk about the election all the time, and it probably counts that towards the points.
