Too much yeast? Calc discrepancies

[KYT]

I definitely should have used a blowoff on this one. This was my first time using White Labs yeast. I've used Wyeast once before, and all other batches used dry yeast. So I totally didn't expect this. Just hoping I don't find my beer all over the floor, or ceiling, when I get home!
