Bud not buddy How does bud turn Todd lie around to punish him?

In "Bud, Not Buddy" by Christopher Paul Curtis, Bud uses Todd's own Words against him to turn the situation around. After Todd lies about Bud being a "foster kid" and tries to intimidate him, Bud cleverly manipulates the situation by claiming that Todd's own mother is a "bad foster mom." This not only shocks Todd but also shifts the power dynamic, allowing Bud to stand up for himself and assert his confidence. Ultimately, Bud's quick thinking helps him regain control over the confrontation.
