pops are the sound of distortion, when the volume of the recording goes above acceptable levels. It often happens on plosives, like pronouncing "im-PLO-de", because there's a sudden rush of air when you breathe out and it gets picked up on the mic.
You can avoid it by recording further away from the mic, and speaking louder, or turning down the sensitivity of your microphone. If you're worried about volume you can always amplify the recording after you've said it, and doing that means you don't have to worry about working around pops.
The other idea is using a filter: if you don't have a pop filter, you can always improvise - something like a sock over the mic would work. GOOD LUCK!

the easiest thing is to seriously re-record the audio, everything else is a compromise of quality. you can edit the offending snippets (they're fractions of a second) but you'll also miss out on fractions of words and continuity. otherwise putting the volume of those parts way down, and fading in and out of the click can sometimes work.

Yah, I'm just a failure at figuring out where the clicks come from so when I re-record they generally just show up in another place. I tried to lower the volume and it definitley minimized the strength and abrasiveness of each one. I figure I'll just record over and over again until I get a take with as few as possible =)
