"You can’t BS a BSer” ("You can’t bullshit a bullshitter") is sometimes used in political arguments. The cynical premise is that all politicians are BSers, so that one can’t easily BS them. “Don’t bullshit a bullshitter” has been cited in print since at least the early 1970s.
A similar phrase is “You can’t con a con man.”
