"It has long been an axiom of mine that the little things are infinitely the most important" 

Just a note
Notice that the greater the value of k the closer this distribution approximates a Poisson distribution with mean m. In other words such distributions are relatively symmetrical  although none of them have a variance less than their mean.
For distributions with small kvalues, there appears to be a second mode of very high values. However, this is simply the result of pooling all values to the right into a single group. In other words, these distributions are highly skewed.
