Final answer:
Benedick mocks others' foolishness in love but becomes a mockery himself when he falls in love.
Step-by-step explanation:
The irony in Benedick's statement lies in the fact that he mocks others for being fools in love, but ultimately ends up falling in love himself. Benedick wonders how someone who has laughed at the foolish behavior of others can become the object of his own mockery by succumbing to love. Claudio, in particular, is mentioned as an example of such irony.
