WATCH: When Sean O'Malley pranked an unsuspecting woman by paying $500 for a bottle of water

Sean O'Malley loves a good prank. The UFC bantamweight has pulled off a number of them on YouTube, with one of his first coming in a collaboration with the ThatWasEpic channel.

The channel deals with pranks, social experiments, and giveaways. Juan Gonzalez, the owner of the page, filmed a video with 'Sugar' titled Picking Up Girls With Suga Sean O' Malley.

Take a look at the clip:

The first part of the video was a segment where O'Malley and Gonzalez would go up to random students and overpay them for food and drink items. The UFC star went up to one girl and said:

"Hey, I'm late for class, is there any way I can buy your water? I'm just late, I'll give you five hundred dollars, thank you."

He then took the bottle of water and ran to 'class' as the girl sat there speechless. She did not understand why a random stranger paid her $500 for a bottle of water that would not cost more than $2.

Both Sean O'Malley and Juan Gonzalez repeated the prank on a number of unsuspecting college students and filmed their priceless reactions for the video.

Sean O'Malley almost got 'slept' for towing a stranger's car for a prank

The pair later collaborated again for another prank video. This time, they hired a tow truck and stood near a gas station, pretending to tow away people's cars before surprising them with $1,000.

One of the men whom they were pranking became extremely defensive when Gonzalez and Sean O'Malley told him they were going to tow his car. After it was explained to the man that they were filming a prank video, the man revealed that he would have started swinging if they tried to tow his car:

"Bruh you almost got slapped bro. That's crazy bro, 'cause I've been to prison for assault twice already."

Juan Gonzalez then asked the man if he would have actually fought them, to which he replied:

"If you guys would have tried to hook it up [to the tow truck]. Both of you guys would have probably been slept. I'mma go full boxer, so..."

The stranger was not aware that Sean O'Malley is a UFC fighter and is one of the most gifted strikers in his division. The comments section saw fans thinking out situations of how O'Malley would have knocked the guy out if something did go down.
