Billy Birmingham is an Australian humourist and sometime sports journalist, most noted for his parodies of Nine Network cricket commentary in recordings under The Twelfth Man name.
- Affably Evil: Max Walker is affable, but willing to commit acts of violence and obscenity in order to get his job back. The real Walker enjoyed this version of himself.
- As Long as It Sounds Foreign: He loves making PunnyNames using Australian English phases.
- In My Language, That Sounds Like...: Those Punny Names sound quite plausable (as some are takes on real names)
- Insistent Terminology: "That's not Canary Yellow, that's Australian Gold my friend and don't you fucking forget it!"
- Not Even Bothering with the Accent: When trying to pass himself off as West Indian Michael Holding, Max Walker doesn't bother to alter his voice at all, except for "mun" (man).
- Ripped from the Headlines: As well as inventing wacky shenanigans, Birmingham exaggerates actual incidents in Australian sport, such as Tony Greig losing a key down a large crack in the pitch in Perth (Birmingham has him lose a shoe) and Bruce Reid's constant injuries (he snaps in half in Still The 12th Man). Bill Lawry...This is Your Life credits Lawry with nailing Richie Benaud's shoes to the floor; while that did happen, the prankster was actually Frank Tyson.
- Something Only They Would Say: At the start of Wired World of Sports II, Max Walker gets a call from Richie Benaud; however, he doesn't believe it's him because Richie has every reason to hate him - and does.
Richie Benaud: Max, it's Richie Benaud.
Max Walker: Yeah, right, who is it?
Richie Benaud: I told you, it's Richie Benaud.
Max Walker: Nah, fair dinkum, who is it?
Richie Benaud: Max, shut the fuck up! It's me, you dopey bastard!
Max Walker: Richie! It is you!
- Totally Radical: Invoked in-universe in Boned when the commentary team tries an image makeover to appeal to a younger audience and makes cringe-worthy attempts at hip-hop slang. Richie uses the malapropism "homos" instead of "homies" and refers to Andrew G from Channel V as Andrew V from Channel G (and as Andrew points out, he wasn't even working for Channel V anymore at the time).
