What's another term for overly ambitious?

Dehumidifying Vancouver

So we have a flood in our apartment building and for the 3rd time, yes, the water is on our floor and in the walls of our apartment. So we have the disaster recovery dudes come in, rip up carpets, drill holes in kitchen cabinet toe kicks, put 3 industrial strength fans in a bedroom and the kitchen. and put a huge dehumidifier in the bedroom. The disaster recovery guys are typically fun guys, they cheerfully rip up your home and warn you to keep the windows closed, or else the dehumidifier won't work - it will "dehumidify Vancouver" before it will take the water out of your room if you leave the window open.

Now there's a term! Dehumidify Vancouver. The mere thought brings to mind many other fun overly ambitious terms like:

* boiling the ocean
* solves all our problems
* hole in one
* self-appraisal
* honest feedback
* getting your ducks in a row
