This viberza commercial nails it. Bowels more then any other body part is like another person always demanding “get to the bathroom” or “nope I am fine” etc.
Who is your bowels? I have to go with Homer Simpson.
The bowels in the commercial is Illena Becker. No idea who other actress is.
Updated. Other actress who plays the person who has bowel troubles is Lois Atkins.
