Ode to Even

My ode today is to our even friends
To every other integer a pair
Providing odds with sorely missing ends
When split in half, results are clean and fair
Oh, even numbers, let me count the ways
In which you double the expected gain
I wouldn't deign to damn you with faint praise
You are for every oddity its bane
It may be even that the subject's odd
Still, don't you tell me that this is for naught
