premise: Susarion (Greek: Σουσαρίων) was an Archaic Greek comic poet, was a native of Tripodiscus in Megaris (see Megara) and is considered one of the originators of metrical comedy and, by others, he was considered the founder of Attic Comedy. Nothing of his work, however, survives except one iambic fragment (see below) and this is not from a comedy but instead seems to belong within the Iambus tradition.
hypothesis: Funny dramatic poetry is the specialty of the Greek poet named Susarion. 
reason: We don't know if his poetry was both dramatic and contained comedy.
