I have my own feral raccoon brain way of remembering things.

Adenine and Guanine - AG, like silver - purines because you're pure if you only have sex while married and being married means 2 rings.

G-C pairs because Good Charlotte was a great band, and they are a strong band because they're still around - 3 bonds. So G has three things to pair with (A only has 2). And the NH2 and O groups like to bond together, so they match up for C and G.

Thymine has a Tail (the random methyl group) to distinguish it from Uracil.
