For my English assignment I have to find a grammer error and make a grammar lesson out of it. I found a sentence in a book and it says, "Of all the stupid things to point out Of course they were vultures." Is there anything wrong with the sentence besides the capitalization error? Please help me!!! I'm so lost I think there should be a comma, semicolon, or colon somewhere in there ...HELP

Of all the stupid things to point out, of course they were vultures.

Crikey, Ashley, where do I start?

Pick a new sentence, mate.
