I've been doing a lot of geo-related work lately and confounding latitude and longitude was a regular source of logic errors. Only useful for North America, but my mnemonic for lat/lng is "latitude has a positive attitude". It doesn't necessarily help when identifying which is which on a map, but when using them for calculating proximity or drawing polygons on a map it works every time.
