Consider The Five Brothers' Disguises (Situational Irony)

In their 13th year of exile, the five Pandava brothers and Draupadi decide to go in disguise in a fellow king's court. These disguises are all ironic given their real identities, providing one of the few explicitly comic episodes in this epic. Yudhisthira, for example, poses as a brahmin who is also a skilled gambler, ironic because gambling is how he lost everything and was exiled in the first place. Draupadi becomes a maidservant, ironic because she can still enjoy similar freedom to what she enjoyed as a princess, but at the exact opposite end of the social ladder. Arjuna poses a eunuch and Bhima as a cook, both meant to provide winking counterpoints to their real identities as deadly warriors, inverting their hyper-masculine identities by assuming more feminine roles.
