How about an impatient 'fingers tapping on table' smiley?

Please please please please please!

That would be so cool. There's no smiley here right now that shows lack of patience. Maybe somebody could create one that looks really impatient, with a fingers drumming on table graphic. something like that.

we should have this one:

it also gives the impression of evil plotting.

I bet Lila64 knows where to find an impatient smiley.
