Oliver follows through with his stunts. Like the time he bought a huge amount of student loans and forgave them all.
Or the time he proved how easy it is to get a religious tax exemption... by successfully getting his studio declared a church (Our Lady of Perpetual Exemptions, with first Mega-Reverend Oliver).
Or the time he bought that HillaryClintonIllness website domain and replaced it with weasels doing the do.
