1209348756
When you have run out of number combinations like 1234567890 or 0987654321 or 1029384756 so you type the two first letters and then the two last and then the next two and then the next two and so on. Then you end up with 12 09 34 87 56. If you figured this out, you must be as bored as hell can make you.
I was bored because I only had 3 out of the 2000 words we needed to type for the essay in Language Arts class. I typed every known combination. qwertyuiopasdfghjklzxcvbnm, plokimjunhybgtvfrcdexswzaq, 0987654321, 1234567890, 1029384756, and then 1209348756. I forgot the others because the teacher made me delete them.
