Twice the fun, twice the trouble.
At Christmastime they cost double.
Twins are great, twins are neat.
Knowing who is who is such a feat.

A brace of twins, a two-fold pair.
The same face, the same hair.
A base of two, binary, a duet.
You can’t tell them apart, I bet.

A couple, a twosome, a deuce.
This one and the other, I deduce.
A duo, a couplet, and simply two.
You’re like me and I’m like you.
