There Once Was An Old Man From Providence

Creative players keep us honest:
if we mess up, then they'll be on us!
The Dog of Dreams
wields giggling screams:
just witness their Limerick contest!

We hate to show our cowardice,
but their humor comes sans notice!
We'd join them in play
but they keep us away
with their dreaded Terms of Service.

Can we survive the horrible pun?
Is there escape from what has begun?
Or have they unleashed
some horrible beast?
Damn, you guys are fun.
