Oh I feel your pain, but my experience wasn't quite that dramatic, though I give it a few more points for pain-in-the-a$$ factor.
The first day I tapped my first ever keg in my first shiny new kegerator, I didn't bother with hose clamps either. I went to bed content that I was in beer heaven.
In the morning, I noticed some liquid pooling around and running out where the tap tower met the top of the kegerator. WTF? I followed the liquid and saw that it had run down the back of the kegerator, but not enough to get on the floor thankfully.
I popped the lid off the tower and saw the tiniest bit of beer just hissing ever so slowly out of the tap shank inside. It ran down the interior of the tower, got through the seal, out and across the top and down. But it gets worse.
The beer found its way UNDER the top of the kegerator. I had to disassemble it, unscrew the laminated particleboard top and there found the day's project: cleaning the beer out from under and around the plastic seal that separated the top from the inside chamber. It was about a 4 hour job to get it all. I didn't want any hint of nasty, stale, disgusting frat house basement smell anywhere in my home. I'm a friggin adult, after all.
Lesson learned. Hose clamps = cheap peace of mind.
