Brock Lesnar, Undertaker Once Had Unique Exchange At UFC 121 (Video)

Brock Lesnar and The Undertaker will square off Sunday night in the main event at WWE SummerSlam. Their clash at Barclays Center in Brooklyn, N.Y., hardly marks their first confrontation, though.

No, we’re not talking about WrestleMania 30, when Lesnar conquered The Undertaker’s undefeated streak, handing The Phenom his first loss in 22 career matches at The Show of Shows. And we’re not talking about some of the other times they’ve clashed in a WWE ring.

For perhaps the duo’s most unique dispute, one must look no further than UFC 121 on Oct. 23, 2010.

Cain Velasquez just defeated Lesnar in mixed martial arts competition to win the UFC heavyweight title. As Lesnar walked past The Undertaker, who was present as a spectator, the two engaged in an epic staredown, with ‘Taker muttering the words, “You wanna do it?”

The dispute, of course, set the Internet on fire and fueled speculation that Lesnar inevitably would return to WWE for a match against The Undertaker. Those predictions, of course, proved accurate.
