Ok, first some ground rules:
1. The code must have been written by YOU.
2. Only code that have been written counts. Code that is managed by you does not count.
3. The code must have already been written. Even if your current project will eventually be your biggest, if you've so far written less code than another project, then the number of lines from the other project(where the code has already been written) counts.
4. If you are working/have worked in colaboration with other people, then the number of lines of code that you have written counts.
Whoever has written the most lines in any project wins forum bragging rights for 2009.
Myself, my biggest project to date has been 174 lines. Took me about 2 months, but dayum, what a marvelous, thoroughly enjoyable experience!
Let the games begin!
