the Fiercest Sibling Rivalries in history
Coaches John and Jim Harbaugh may be getting all the attention this Super Bowl weekend, but when it comes to brotherly competition, they've got nothing on some of the greatest sibling rivalries of all time:
1. Romulus vs. Remus

While these legendary twin brothers laid the foundation for Ancient Rome, they bickered constantly over who had the sweeter ass—though it is clear from the statuary of the period that it was Remus who was like, Ka-blammo!
2. Orville & Wilbur Wright vs. Mortimer & Edgar Wright

Orville and Wilbur Wright designed the first airplane alongside their two lesser-known brothers, Mortimer and Edgar, but the four brothers were divided over whether the invention should be used as a flying machine or a washing machine.
3. Andre Agassi vs. Pete Sampras

In perhaps the most startling instance of competing brothers in recorded history, DNA testing recently revealed that tennis superstars Andre Agassi and Pete Sampras are not only full brothers, but also conjoined twins.
4. Luke Wilson vs. Owen Wilson

Throughout the early-to-mid-2000s, the Wilson brothers battled it out to see who could be the first to drive himself into relative obscurity by appearing in a series of mediocre romantic comedies. As of 2013, the winner has yet to be determined, and no one cares anyway.
4. Eli Manning vs. Peyton Manning

Following a particularly large dinner, these two elite quarterbacks got into a heated argument about who could eat more hard boiled eggs on a full stomach. Eli won and then threw up all night. Peyton also threw up all night.
5. Lyle Menendez vs. Erik Menendez

In 1989, the Menendez Brothers simply could not agree on who was better at killing their parents. One evening, after a lot of macho posturing and demonstrations of their skills, the siblings decided they were being silly, had a good laugh, and agreed that they were both really, really good at it.
