I had to dig this thread out. How well I can do each of the character's voices on a 1-10 scale:
Homestar Runner: 3 (of all the main characters, his voice is the hardest for me to do - I just can't get his speech impediment and tone down at all - but I'm more like an 8 on the Powered By The Cheat version of him... that one's fairly easy)
Strong Bad: 4 (I'm closer to the real thing than Homestar, but still not very good at it - 9 for the PBTC version, though... thanks again Mike Chapman
)
Strong Mad: 8 (very good - with a bit more practice I could probably do SM almost perfectly - yelling out 'THE CHEAT IS SO A COW!!!' and 'I HAVE A FUNNY HAT!!!' is so much fun)
Strong Sad: 7 (certain quotes I can do pretty well, especially the faster ones in Caffeine and 'I'm sad that I'm flying...', though while good, my SS needs a bit more work)
The Cheat: 7 (you'd be surprised how varied some of his phrases actually are, though I can do 'Meh' just fine)
Bubs: 6 (I'm average at Bubs for the real version, but on the PBTC version a 9 - 'hey Strong Bad! You just jumped over some of my buses')
Coach Z: 6 (again, another character I'm only just decent at, though I think I have 'JAEERRRRRBBBBBBBB!!!!' down pretty well)
Marzipan: 4 (yes, I'm not any better at a girl's voice than SB or Homestar - I can kinda get her a little bit but not very much... 8 for the PBTC version
)
Pom Pom & The Poopsmith: N/A (for obvious reasons
)
The King Of Town: 8 (of the 12 main characters on the site, figures the one I can get down the best is everyone's least favorite...
)
Homsar: 5 (DaAaAaAaA.... I'm an average piece of real estate)
And some others:
Senor Cardgage: 9 (it's weird that my Strong Bad is weak, yet I can get Cardgage down almost perfectly.... makes no sense at all)
Blue Laser: 9 (I think I've got his 'Well, that's JUST GREAT!!!' and 'FAN-FREAKING-TASTIC!' particularly down)
Eh! Steve: 8 (it's hard to remember everything he says... so many sophisticated phrases
)
Marshie: 4 (another one I kinda have trouble with, though I'm slightly better with his phrases in the Malloween game, like 'LEVEL UP!' and 'Dang it!!!')
Stinkoman and 1 Up: 3 (both of these give me quite a bit of trouble, just as much as Homestar)
1936 Homestar: 5 (I can get kinda close at times, but it's hard to do him well)
The Announcer: 4 (out of all the more minor characters voices, this is probably the one I wish I could do most but can't - 'And coming in at #4, it's Strong Bad with 'Song About Sibbie!!')
Larry from Limozeen: 6 (I could probably get this voice with more work if I could remember it)
Rather Dashing: 7 (another example of my actually being passable at doing British-sounding characters)
