This video makes me think of the work week. You run hard all week...and then life throws you off anyway! :) I think this gerbil actually likes doing this. It's that or he can't seem to learn his lesson. Either way it's kind of funny. Of course if you have a gerbil, it will probably sleep all day and then do this all night while making sure you hear how much fun he's having.
I saw another wild video. It's a little gross but cool at the same time. Look below at the ants that made a "human" or I guess "ant" rope to get to a wasp nest they wanted to get into. Not sure what was so great in the wasps nest, but then I'm not an ant.
Glad it's not my house. Some major fumigation is needed.
