Downtown no Gaki no Tsukai ya Arahende!! (ダウンタウンのガキの使いやあらへんで!! Dauntaun no Gaki no Tsukai ya Arahende!!?, lit. "Downtown's 'This is no task for kids!!'") is a Japanese variety show hosted by the popular Japanese owarai duo, Downtown. This TV program began broadcasting on October 3, 1989, and is a popular comedy show in Japan.

The "No Laughing" Batsu Game itself (broadcast annually during the New Year's Holiday) was first introduced in 2003. The premise of each "No Laughing"-punishment game is, the losing members of the cast have to endure many compromising, absurd, generally ridiculous situations for a long period of time (up to 24-hours, thus far) but must refrain from laughing at any of them. Whenever someone does laugh, and he is caught by A Watcher, the announcer of the game will declare that person as having just become "out" (アウト or a-u-to in Katakana); immediately afterwards, the appropriate number of "hang-men" will come out to mete the rule breaker's punishment. (To date, this has been executed via single strikes on the buttocks {or somewhere in that area} with a weapon — one which does not change mid-game.)

Just wondering if anyone else watches this show?
It is hilarious.

Ohh I love the "Don't Laugh" shows .clap. . I always cracked up so bad seeing those guys in action. The first I watch is the high school one and it's awesome

Same here, I watched the high school one first; so hilarious. The hospital one where they dress up as nurses was just as good.

I got all the DVD's from a friend recently, some of them go for five hours :O
I've seen Newspaper Agency and High School,
Currently Half Way through Hotel.

I LOVE THIS SHOW!
DOWNTOWN is like the best comedy duo in the WORLD! I love their comedy sketches, stand up comedy and their funny games. My favorite is those Gaki no tsukai 24Hour No-laughing segment. Along with CocoRico and Yamazaki Hosei, they are the best 5.

I definitely want their full show in english sub. I can only find some on youtube. Not the 24h no-laughing, since I have those already, but their regular skits.

All of 'em are good. Love 'em all! Credit goes to everybody for making the show a comedy marvel, but from my point of view, the biggest key to its success is the Downtown Duo. (Matsumoto Hitoshi & Hamada Masatoshi)

Here is a pair of man capable of making you laugh with just the simplest of suggestions.

In my opinion, the laughing factor for Matsumoto is his face and his occasional speech with an indifferent attitude. For Hamada, it's his nature as a sadist and the tendency to make lives miserable for everybody else around him. (You have to admit that you're sadist as well if you've laughed at Hamada's actions.)

Needless to say I love seeing Yamasaki Hosei (almost always) gettin' slapped by Chouno Masahiro. His face showing the aftermath is priceless.

Haha yea, Yamasaki always ends up making the rest of the members get OUT'd in the build up to him getting slapped by Chouno
.lol.
