Cheesy Sausage Dip

I can't figure out where I got this recipe from (Cooks.com, I assume).  We just know it by heart at this point.  I have taken this to many potlucks and made it for crowds many times and it never disappoints.  The only rule is, you must invite me over to eat this with you!

Cheesy Sausage Dip
adapted from all over the place

1 lb Velveeta, cut into cubes
1 package cream cheese, cubed
1 can Ro*tel Original Diced Tomatoes & Green Chilies
1 lb sausage
1/2 lb ground beef

Brown the meat in a large skillet and drain.  Pour into a crock pot.  Add the rest of the ingredients and stir to mix.  Place crock pot on High for at least an hour until cheese is melted and hot.  Stir frequently.
