3shirtsWow, where to start. Your delivery is slow and monotone, the voices are annoying and you fucked up the final punchline anyway. The first thing the frog said to the alligator was "I am a wide mouth frog" so pretending not to be one just doesn't work.
The joke would work better if you flipped it round so he always asks "who are you and what do you eat" first and then when they reply, he says what he is.
The first joke is surreal but not funny enough to pay off the long drawn out build up. Needs to be short and punchy.
