Improbable, not impossible.
Some people online are talking about how Bryan Cranston is halfway to an EGOT. I love Cranston and especially Breaking Bad (although his acting along with Jane Kaczmarek on Malcolm was seriously terrific). I’m more intrigued (although I’m about 3 years late) on how close Trey Parker of South Park is to the EGOT. If Phil Collins hadn’t beat him out for an Oscar in 2000, the voice of Cartman would have an EGOT. Wow.
