Orbit vs. Chris Archer: Round 3

North Carolina-Duke, Red Sox-Yankees, Michigan-Ohio State and nowChris Archer-Orbit will be recognized as some of the biggest rivalries in sports.

The two have been in an all-out prank war this week, starting with Archer's "declaration of unfriendliness" on Monday and continuing with Orbit's "peace offering" on Tuesday.

Before Wednesday's game between the Houston Astros and the Tampa Bay Rays, Archer presented Orbit with a degree from the "University of Raymond," a nod to the Rays' mascot Raymond. While the mascot was distracted, Archer and his teammates bombarded Orbit with water balloons.

Orbit returned the favor while playing a game of "Orbit says," and tricked Archer into admitting he just farted.

We won't have to wait long to see the next chapter of their rivalry, since the Astros and Rays play the finale of their four-game series on Thursday.
