Will Arnett has not publicly revealed the name of the comedian he and his co‑hosts kicked off the SmartLess podcast; the identity is still a mystery.

What Will Arnett Actually Said

In a January 2026 interview, Arnett explained that:

  • A “very famous” comedian was booked as a guest on SmartLess.
  • He described the person as a “f---ing rank a--hole.”
  • He, Jason Bateman, and Sean Hayes decided to cut the interview after about 10 minutes, thanked the guest, and ended it.
  • He teased that people would be “blown away” if they knew who it was, but he did not give any name.

So, who was it?

Right now, all that’s known is:

  • They’re a “very well‑known” comedian.
  • The episode never aired.
  • Fans online are speculating and playing detective, but there is no confirmed, reliable identification.

Because he hasn’t named the person, any specific name you see on forums is just rumor and shouldn’t be treated as fact.
