By hook or by crook

 Last night I learnt another interesting idiom from Alex. It's 'by hook or by crook'. Have you ever heard of it before? Do you know what does it mean? I'd like to share my examples. Let's see if you can guess its meaning. Otherwise you can always check Alex's lesson to find out. 

Here are my examples:
