Dumb sayings

I think it's funny when someone says, "Do yourself a favor and (do whatever they say is doing yourself a favor)".  Like that person knows that I would be doing myself a favor by doing what they say I should be doing.  Dumb.  I prefer something like, "You should check this out.  I think you might like it."  I would prefer it even more if the reason why I would like it was stated, too.  I don't know... It's just a lot better than someone telling me to "Do yourself a favor."   I just can't take it seriously.  I think I can determine my favors myself, thank you. (LC)
