Selfishly, I like to imagine that Justin Bieber was blasting Bobby Shmurda's "Computers" verse when he was tweeting about fighting Tom Cruise. The truth is no one knows why the Biebs was joking about running a fade with the actor. Yet it did prompt people to think about other celebrities that dramatically exceed them in age and take to social media to see if these stars wanted to scrap.

While some people were enjoying whatever peace and solace their Sundays bring them, Justin Bieber was ready for the opposite. The singer ended his weekend by asking UFC president Dana White if he could set up an MMA fight between himself and Tom Cruise.

"I wanna challenge Tom Cruise to fight in the octagon," Bieber tweeted. "Tom if you dont take this fight your scared and you will never live it down. Who is willing to put on the fight? [Dana White]?"

Of course, there were people on the internet that missed the sarcasm and quickly reminded JB that the 56-year-old Cruise is 31 years older than him. This only added to the humor.

Proven by the way he was able to convince all of America that the bowl cut is acceptable, the Biebs is a cultural icon. As a result, users began to follow his lead by challenging random celebrities that have 30-plus years on them.

The next day, Bieber finished the joke by posting a modified video of Cruise's fight scene in Far and Away. Despite boldly issuing the challenge, Justin's face was put on Cruise's losing opponent, forcing the singer to tweet: "Damn Tom this didn’t go as planned."
