The good people at Nerdist, an online “nerd media empire” started by Chris Hardwick, made that dream come true. As part of a celebrity bowling series, they organized the match, which benefited St. Jude Children’s Research Hospital as well as anyone who watches footage. Because it was hilarious.

The video is NSFW, and therefore can’t be embedded here, because of all the trash talk. Also, there’s something rather unsettling about Kartheiser’s — not Hamm’s — beard. As comedian Pete Holmes told him, “You look like the hobo that killed Pete Campbell.”

So watch it over at Nerdist’s YouTube channel.
