Inventive new ways to wake up 101
Don't throw out your old mobile phone! If it has an alarm system on it with a vibrator that goes off at the same time as well and you can set it to silent or else replace the alarm with an empty voice recording... then wrap it in a plastic lunchbag, set it for when you want to wake up, put it between your legs (obviously must be female to pull this off succesfully) and enjoy!
Why waste money? ;D
