I think the biggest problem is the generic entity you are trying to use which doesn't match the entity return type. Try this:

public mmBindingList<MyJokesEntity> GetMyWinDings(string type)
{
     return this.GetEntityList<MyJokesEntity>("GetMyWinddingsByType",
          this.CreateParameter("@type", type));
}

Assuming that MyJokesEntity is a defined Entity in your business objects library.
