Three smells.....

There are three things that smell so bad you want to gag,
yea, four things which make your nostrils flail in pain.

A rotting cantaloupe that has sat in the sun,
when fresh it has a wonderful aroma,
but one sniff after it has gone bad and you'll be in a coma!

A dead skunk that lies in the road,
bloated in the sun. the smell can erode,
it's defensive odor is meant to protect,
but once dead my nose it infects!

Mildew, such a small sounding thing
but when it is on clothing, what a smell it doth it bring,
musty and funky the smell makes you wheeze,
as it invades the nasal cavities!

Humans perspire when we get hot,
a sweet smelling scent it is not,
without deodorant, I fear gas masks would be our attire,
to help keep the smell absent or else we'd expire.
