How do you remove grease from concrete?

Last night I was cooking on the patio and some grease spilled over from the pot on to my concrete patio. I toke some water out side, threw it on the skill and began pushing it off the porch, (I just want to add that I have had enough to drink to say, "ah.. the hell with it, I'll clean it up in the morning"

Wrong! Double Wrong!

Woke up this morning and there was grease all over the concrete, after searching the interwebz I came to discover that I might as well prepare my anus..

So, the first thing I did was use some good ol' dawn, (should've known better),... WRONG

from what I can gather from the interwebz is that the first thing I shoulda done was throw kitty litter all over the grease.. well, I don't own cats, was WAY to drunk to be going anywhere and so was everybody else at my place..

So here is where I sit now, got some degreaser and powder laundry detergent outside sitting till it forms a paste.

After that, it's in tOB's hands..

So fellas, what is the best way to get set in grease out of concrete?
