This great proboscis is my pride and joy,/Since a fine nose is the unfailing mark of a fine man, witty, good-natured, brave,/Courteous and forgiving.

These lines are quoted from the play "Cyrano de Bergerac" and said by the main protagonist Cyrano de Bergerac, addressed to Busybody.

Explanation:

These lines are from the play "Cyrano de Bergerac" by Edmond Rostand. It revolves around the hidden love story of the protagonist Cyrano for his cousin Roxane. But it did not have a happy ending nor is it a happy love story but rather a tragic story of hidden love.

The lines are said by Cyrano about his nose in Scene I. iv. He has a huge nose which prevents him from being confident and openly proclaiming his feelings for Roxane. Here, he is seen proudly boasting in front of everyone that his nose is better than anyone's, that "a fine nose is the unfailing mark of a fine man, witty, good-natured, brave, / Courteous and forgiving." But in reality, he was conscious about it and thus had to hide his feelings for Roxane too.
