What is this picture trying to say?
Edit: @Hugh solved this quickly so I'm adding two more that I imagine are a little more cryptic but still in the spirit of rebus puzzles.
Edit2: Modified #2 and #3 to be clearer.
In @UnidentifiedX's words,
For those who don't know, a rebus is where words are represented by a picture and you try to figure what word or phrase the picture is trying to represent.
