There are a lot of powers in the PHB--and I mean a lot--that have the effect of knocking the target prone if the attack hits.
I also notice these powers have no restrictions about the type of target that can be toppled. Is there any broad rule that protects big creatures from being knocked over (other than the attack in question missing, of course)?
I guess seeing a halfling flip a colossus, an ancient dragon, the tarrasque, or what have you would be amusing once in a while, with it groping its foot and falling over like something out of a Tom and Jerry cartoon, but seeing it routinely happen in every encounter with an enormous monster would cloy quickly.
