My husband and I call it the "Murphy Run" because as soon as he is done he gets down and runs through the house like a mad man!! He rolls on the rugs, bites anything he can get his teeth on and trys to drag it along with him and even does what we call the "growl by" where he runs past you and growls and barks. I think it is just them feeling FUNKY and FUN after bathtime - you have got to love it - it is so much fun to watch him. LOL!!!
