A 16-year-old Bosnian Taekwondo champion, Kerim Ahmetspahic, set a new world record by smashing 111 cinder blocks in 35 seconds, using only his head as the weapon with which to do the job.

Here’s a video of the young man utilizing a crazy technique to make his mark on the Guinness Book of World Records.

Cue up the “using his head” jokes.

In all seriousness, this was quite a fantastic feat accomplished by the young Bosnian martial artist, who isn’t quite satisfied with the final result.

“I still have more power,” he said, per the Daily Mail. “I wish to thank all the people who helped me achieve this – my parents and my coach Edin Kajevic.”

His parents must be awfully proud. Also, someone get him a neck rub, stat!
