From: Pokemon Breeding Guide

The Unbreedable:
Not every Pokemon is capable of breeding, even with the aid of ditto. For Legendaries, there is good reason. For some of the others, its simply they are not able to. Pokemon like Munchlax and Pichu are “Baby Pokemon”, earlier forms than could originally be found.

It is worth noting that Ditto cannot breed with another Ditto for a Ditto Egg.
