What are some tips or techniques for memorizing lines?

Thanks.

Say them out loud.
Understand the sense/meaning of the lines and as they fit into the whole.
Repeat them at least ten times in a row, carefully and deliberately.
Repeat them to another person, even if it's a baby -- or even to your dog/cat.
Say them in front of a mirror.
Sing them.
Whisper them.
Clap your hands while saying them with a rhythm, like a cheer.
Write them down/print them on paper.
