Lucky Egg Experience Trick (Don't Catch Fearow!)

Save a lucky egg, an incense, and a bunch of pokemon to evolve.
Pop the egg and the incense, and start evolving the pokemon. The egg will give you double experience for any pokemon you evolve or catch for 30 minutes.

Bonus: When a pokemon is entered into your pokedex for the first time, you get experience.
If you evolve it with a lucky egg activated instead of catching it for the first time, you can get double experience for it.
This works well for evolved forms of common pokemon such as raticate, pidgeotto, fearow, etc.
