In an embarrassing, drunken rampage, Lane was featured on episode 8 of The Ultimate Fighter: Team Carwin vs. Team Nelson in a segment that saw him continually plead "Let me bang, bro," to fellow fighter Michael Hill. During the 45 seconds or so that he continued to repeat the now sensational slogan, Lane's demeanor became markedly more desperate as he began to cry while continuing his demands. The segment was so memorable that it immediately sparked much attention on the internet, including a meme.
