Looking to add yet more drama to one of wrestling's biggest ever situations, legendary announcer Gorilla Monsoon produced one of the best commentary lines in history. As Hulk Hogan and Andre The Giant squared off at WrestleMania III, Monsoon declared that the 'irresistible force' had met the 'immovable object'.
Such a phrase has become timeless in pro wrestling, it's one of those lines that will just never stop being relevant. Analysing many of the most important feuds in industry history makes that clear, there are numerous examples of wrestlers being portrayed as equal forces butting heads.
Building an even situation is easier said than done. Sometimes, one performer is simply stronger than the other, or perhaps fans favour one man more. This can lead to an imbalance of sorts, which doesn't do much for the claim that things are decidedly equal.
Let's take an in-depth look at 10 situations that undoubtedly lived up to Monsoon's phrase, between wrestlers that were often the spitting image of one another...
10. The Big Show Vs. The Great Khali
At WrestleMania XXIV, The Big Show faced the diminutive boxer Floyd Mayweather in a special attraction match.
The bout provided WWE with a lot of mainstream coverage, and must be considered a successful spectacle, all things considered. Less than a full month later, Show had a different challenge on his hands.
For the Backlash pay-per-view, WWE officials decided to pair one giant off with another. Standing toe-to-toe in the middle of the ring at the event, The Big Show and The Great Khali looked like two mountains about to wage war. It was like something out of a movie, which was likely the exact visual WWE wanted to create.
Going 8 minutes, it was never going to be a technical masterpiece. However, Show vs. Khali didn't need to be, it simply had to answer the question over who was superior.
Big Show would win the match, even though the situation was more even away from the cameras backstage.
Chris Jericho has often told about a battle in the locker room between both men, one which must have been a scary sight for passersby.
