Mae Daf y gath yn gwylio’r teledu. Fel arfer, bydd hi’n gwylio rhaglenni am fywyd gwyllt, a dychmygu hela’r adar yn aflwyddiannus.
Ond y tro yma, mae hi’n gwylio rhywbeth arall.
Mae dyn swnllyd, tew ar y sgrin.
Mae e’n ailgymysgu caneuon opera yng nghwmni mintau o ystifflogod bio-ymoleuol.
Teitl y rhaglen yw “Sesiwn DJ Dyfnforol Bryn Teribl”.
Pa mor alluog yw’r ystifflogod?
Dim o gwbl.
Pa mor alluog yw Bryn Teribl?
Dyn ni i gyd yn gwybod yr ateb i’r cwestiwn hwnnw.

Television
Dave the cat is watching TV. Usually, she will watch programs about wildlife, and imagine unsuccessfully hunting the birds.
But this time, she is watching something else.
There is a loud, fat man on the screen.
He is remixing opera songs in the company of a host of bio-luminescent squid.
The title of the programme is “Bryn Teribl’s Deep-Sea DJ Session”.
How competent are the squid?
Not at all.
How competent is Bryn Teribl?
We all know the answer to that question.
