Nothing this big is allowed in my house unless it can wash the dinner dishes. Any other option involves me asking it/them to leave followed by multiple gunshots or me screaming like a little girl as I run away.

Very true. One of the few animals I refuse to handle. Aggressive, fast, intelligent, and venomous is a bit much. There is only one documented instance of a person surviving a black mamba bite without receiving antivenin.

Not sure but methinks every sane human on the planet would be at least a bit scared. That thing looks like a Black Mamba, many lists place it at the top for deadly and most put it well into top ten for most venomous. Very aggressive and extremely fast, (faster then a man at full sprint so you better be driving) the stuff of many legands of which a few are most certainly true. In any case 100% mortality rate if untreated by even a glancing strike from an animal that commonly puts about five to ten strikes to the face and arms at five to ten times the killing dosage suggests it could kill a fucking rhino if it so chose.
