The applications of unusual outfits would have also entertained the Athenian audience.
Examples of slapstick can be seen both in The Frogs and in The Wasps- a good example of slapstick humour from The Wasps occurs in the parados, when Procleon is trying to escape from his imprisonment by escaping through the window, using a rope. On seeing Procleon's attempt to flee, Anticleon tugs on the rope to get his father back inside, and his slave Xanthias beats Procleon from below with the "harvest-festival affair." Procleon is dangling helplessly in the air, while getting thoroughly beaten- the audience would have had a good laugh due to the absurdity created by this scene. In The Frogs, we can see the usage of slapstick just before the parabasis- Xanthias and Dionysus is being beaten to prove "which one of them is god." .
An example of sexual innuendo is apparent in the prologos of The Frogs, while Heracles and Dionysus are having conversation together. When Dionysus says "I was on Cleisthenes' ship-" Heracles replies "Clei-! Saw a good bit of action, I expect, one way or another?" this is a sexual innuendo, because Cleisthenes was renown for his feministic character- it is suggesting that Dionysus had a relationship between Cleisthenes. When it comes to explaining Aristophanes' use of humour in his plays, parody is something that must be taken into consideration, since he used it so cunningly.
Parody is used in The Wasps during the prologos, when Procleon is attempting to escape by binding himself under a donkey. This is a parody of Homer's Odyssey, when Odyssey and his men escaped under the nose of the blinded Cyclops by tying themselves under a group of sheep. Another example of parody is also seen in The Frogs, as we enter into the agon- Aeschylus parodies Euripides' modernistic poetry by the use of castanets, and Euripides sings out "flat-a-thrat-a-flat-a-thrat" loudly to parody Aeschylus' rather noisy poetry.
