Moxibustion. What moxibustion is from Wikipedia:
A traditional Chinese medicine therapy using moxa made from dried mugwort. Practitioners use moxa to warm regions and acupuncture points with the intention of stimulating circulation through the points and inducing a smoother flow of blood and qi. There are several methods of moxibustion. Three of them are direct scarring, direct non-scarring, and indirect moxibustion. Direct scarring moxibustion places a small cone of mugwort on the skin at an acupuncture point and burns it until the skin blisters, which then scars after it heals. Direct non-scarring moxibustion removes the burning mugwort before the skin burns enough to scar, unless the burning mugwort is left on the skin too long. Indirect moxibustion holds a cigar made of mugwort near the acupuncture point to heat the skin, or holds it on an acupuncture needle inserted in the skin to heat the needle.
Mouth to mouth but not as you'd expect (though there is still a beach involved). The cast do a challenge where they must pass different things between each other using only their mouth.
Sidenote: Does anyone know what happens with Matsumoto at the end? Everyone is really surprised at him and I'm not sure exactly whats going on.
