If there were any doubt as to whether or not it's a good idea to start your K-1 fight by playfully (or intimidatingly, or whatever) kissing your opponent, this video pretty much dispells that notion.
The fighter is Heath "Texas Crazy Horse" Herring, whose bio reveals a 24-12 record. (The last loss was the pictured DQ with Yoshihiro Nakao.) And we have a feeling Herring is not a fan of Brokeback Mountain. But, you know, watch the video yourself.
