My friend gave me this roll of toilt paper. Printed on it are senryu about toilet. TOTO, a toilet company in japan held a contest of toilet senryu, and the winners' senryu are printed on the roll. It costs about $4 a roll, and is sold at a bookstore. When you are in toilet, you read it and supposed to giggle on the senryu. I did read them but not really funny. It is just an expensive joke.
