PS karma here works in weird ways. When you have a lot, you give a lot. So if somebody's joke amuses you, and you give them karma, you by default dump a huge mass of karma on them. So karma tends to grow in astronomical leaps.

You can specify how much you are giving, but it seems stingy to adjust it very far downwards!
edit: See, I bumped your karma by 67142 in 1 go.
PSPS There is a thread about "how does karma work" if you really care.
