Murikuri (むりくり?) is a one-shot manga by Clamp, published in Vol. 4/5 (a special double issue) of Kodansha's Young Magazine in 2002. It is a seinen, one-shot manga. It is a collection of random one-shot where the only reoccuring theme is a pig and his grade-school friend.
Murikuri is a series of several short stories, it is only 16 pages long, in the which we're told 7 comic stories, insane, random featuring aliens, a man conceiving a baby, and a pig.
Many of these stories revolve around sexual desire. The first story involves a girl giving a love letter to a pig. His friend, a grade-school boy, envies the pig because of the pig's height, which allows him to see girl's panties. This same pig appears in another story later in the volume where a group of boys (plus the aforementioned pig) are talking about a cute girl in another class and the pig comments that her underwear has a demon motif on it. Yet another, is about a man discovering he's carrying a baby, which is an unwelcome surprise as it means he and his wife can no longer have sex. A girl argues with her boyfriend (who is a perverted Santa Claus) about spending Christmas together, which he can't do since he has to work. Another story is about aliens beaming themselves into a woman's and gives her an estimation on house repairs which makes her scream.
