The best one I heard recently was "there's two ways to do this trick, with applause or the way we're doing it right now."
The thing I hate most (and it's not really a phrase, it's an action.) is when people get so mad at things because it's not in baby steps for them. Let me explain a little more.
People complain about the patter of an effect or there isn't any patter, there's not a strong enough kicker make a better one, develop the patter for this blah blah blah
you shouldn't use the same patter as other people, including the creator, unless thats the ONLY patter you can think of for the effect, or it fits your performance style like a glove. If you don't like the ending of an effect or the method, create your own, don't complain about something you bought to the creator saying you don't like it.
Create your own stuff guys, I hate these people that need to be spoon fed, a ton of magic starts as an idea that most of the time other magicians finish, learn to create and imagine, don't just buy and perform.
