some of my favourite techniques are: bag/backpack - if the cache is situated near the ground, i just take off my bag, place it on the ground and pretend i'm searching for something. Then i quickly reach for the countainer, and hide it in my bag, where i open it and sign the log. keys - if i'm with my friends i just say something like "guys! Have you seen my keys? I think i dropped them here!" And then we can look under every bench and bush. Also, when you're with friends stealth is much easier.
