A Russian, a German and an Irishman are in a sauna

...stark naked.

The three men sit there for a while, completely nude, damp and steamy, absorbing the hot and completely-non-toxic water fumes.

Suddenly, a white light fills the room, accompanied by a buzzing noise! The Russian and the Irishman look towards the German, and they see that his hand is the source of the light and the noise.

"Sorry!" the German apologises. "I've a mobile (cell phone) built into my hand. Someone's sent me a text."

The German then politely turns off the gadget in his hand, and resumes being damp and steamy.

Not too much time passes before, once again, the room lights up, illuminating the steamy vapours above. This time, it's the Russian's arm that is bright.

"Sorry, men." the Russian says. "Someone's sent me an email. I have a computer built into my arm." He too turns his bionic gadget off.

At this point, the Irishman is furious. He doesn't have any sort of fancy electronics implanted anywhere in his body. He doesn't even have a pacemaker or anything. But! He does have an idea.

The Irishman excuses himself, and leaves the sauna. He wanders along until he encounters a toilet room, enters, and uses the toilet. Afterwards, he takes some tissue paper and wipes his bum - but leaves some of the paper hanging out.

The Irishman then strolls back toward the sauna, a trail of toilet paper trailing along behind him, stuck between his buttocks.

He re-enters the sauna, and exclaims "Whaddya know! Someone's sending me a fax!"
