If you are in Drop D, tune the last string to the A string from the 8th fret. And do the same with every string but +1 fret to the normal tuning. (I know I didn't explain it every well. Hope that makes sense...)

I remember my first erection. I went to my dad and was like "Do I have Aids???". I seriously thought there was something wrong with me.

or you could buy a tuner...

If you have a capo, they can really help. Just put it on the first fret and then tune to drop d. Works on guitar and bass.
