The Vietnam tourism board must be thrilled with Dr. Mike's choice in local cuisine, a beef tapeworm cyst.  

Yes, this game chap makes Andrew Zimmern seem downright finicky. Previously, the good doctor purposely scarfed raw, unwashed meat in order to grow a tapeworm in his guts. Now, join the fun in the bathroom, where he passes his lengthy special friend.

The thing is, he actually enjoys this.
