Malawi bans gas - the other kind.

According to the BBC, breaking wind, stepping on the duck, cutting the cheese, SBD's are going to be illegal in the African country of Malawi. A new law proposed by the parliment would make it illegal to "rip one" in public. This is an effort to "to mold responsible and disciplined citizens."

But finding the culprit may be more difficult. I suggest the old technique of "Whoever smelt it .. dealt it."
