Oh... alrighty then

throwing a sharp pencil at some one so they can get the point

Throwing stables at people who need to hold their horses

C-C-C-COMBO BREAKER!

Throwing a red sign at people who need to stop.

Throwing a sauce pan at someone so they can simmer down

Throwing a star at someone but missing so they can count their lucky stars.

Throwing a rock because I can't find anything else
