pissing in the ocean

a futile attempt; an act which will have very little or no consequence; a very small proportion of the whole

Trying to stop illegal downloading by arresting individual college students is like pissing in the ocean - there is no way they can arrest millions of internet-users.

pissing in an ocean of piss

Doing something totally pointless.

Trying to reason with a psychopathic murderer is like pissing in an ocean of piss.
