Core has ( https://api.github.com/repos/wordpress/wordpress/languages ):

8,830,768 bytes of PHP code
1,836,270 bytes of CSS code
2,034,993 bytes of JS code

Jetpack has ( https://api.github.com/repos/automattic/jetpack/languages ):

3,238,091 bytes of PHP code (36.7% as much)
550,377 bytes of CSS code (30.0% as much)
570,773 bytes of JS code (28.0% as much)

And that includes all our build tools and unit tests, whereas the core repo doesn't.

And --- really? You're going to resort to fat jokes?
