How about.... easy peasy lemon squeezy

we have gone too far, and I tell you why. No saber hacer la o con el culo un vaso o con un canuto, means that sb is so useless that he or she cannot do anything, that she is really clumsy, he writes awfully, she doesn´t know how to draw, even how to do the washing up. I hope this is understood now.
