Felix overhears daniel telling a joke that makes fun of doctors. felix’s mom is a doctor, and felix is offended by the joke. does felix have a legal case against daniel?

if daniel only tell jokes that making fun of daughter and felix somehow offended because his relative is a doctor,:  No,  felix does not have a legal case because offensive speech is protected under the First Amendment.

Even if a speech somehow hurt your feelings, that speech is still protected by the first amendment of united states under the free speech clause. The only exception is the speech that directly advocated for violence or a danger that targeted to certain group or individuals.
