Milkshake

A malted made without the malt
You may think a mistake,
But take a sip - it still tastes great
Though now it's called a shake.

A real one, though, comes with a tin
Directly from the shaker,
A second glass-worth sitting there,
A present from the maker.

You slurp it down, so cool and sweet
And when your straw hits air,
You pour a refill from the tin,
So calmly waiting there.

There's nothing like a milkshake
When you're really in the mood -
A splurge, a treat, a pure delight 
And better than most food!
