Just do it

Birds
Bees
Educated fleas

In Spain, the best upper sets
Lithuanians and Letts

The Dutch in old Amsterdam
Not to mention the Fins
Folks in Siam (think of Siamese twins)

Some Argentines, without means
People say in Boston even beans

Romantic sponges, they say
Oysters down in oyster bay

Cold Cape Cod clams, 'gainst their wish
Even lazy jellyfish

Electric eels I might add do it Though it shocks em I know

In shallow shoals English soles
Goldfish in the privacy of bowls
