got to thinking about it and i think i have figured out what i believe to be the greatest invention of all time now keep in mind that i am a simple minded person,and whille pouring the bridge deck this morning at 4am and waiting on concrete trucks i got to thinking about rechargeable batterys, and this is retarted but what other power source can run your tooth brush, your old ladies vibe, and then pop in the digital camera and take a picture,and after you are done you can put them in a remote and flip through 300 channels of nothing on, and then when you are bored you can stick them in the ol mp3 player and head to the gym. now when all is said and done back to the charger to get ready for the next day. now with all this being said and this is probally a few minutes out of your life you will never get back, but isnt that a bad ass invention. man i need to find a different job.
