In the beginning of 20th century, there was a comet which passed by near Earth and to ward off possible effects that the gases in the comet might have on Earth's atmosphere, pills were sold.
Although that comet didn't cause any noticeable changes in the Earth's atmosphere, certainly the people of 100 years ago and also modern people might be curious as to how comets smell.
Rosetta spacecraft that is currently orbiting the comet 67P/Churyumov-Gerasimenko has analysed the comet's "atmosphere" which among others contains ammonia, sulfur dioxide, hydrogen cyanide but also formaldehyde and methanol. Quite a pungent comet.
