Again, a common misconception... And it also depends on what you consider harmless...
I can direct you to atleast 4 individual accounts where the effects of the bit were medically significant...
Trust me, I used to feel the same way but the reality of it is, is that you can have a bad reaction that points to envenoming, not an allergic reaction...
In at least two of the documented accounts the person bitten suffered from some long lasting effects from the bite...
You may also want to contact Wolfgang Wuster and Bryan Grieg Fry about the venom of a hognose snake and its potential...
Here is a photo of a bite from a harmless hognose snake...
