There are several others out there you might want to check out. The Knit Wits is extremely witty.
Brian, you might want to contact them to see if they might do some transcripts. This is a couple who has adopted 2 little girls after fostering many. I think the oldest little girl [I think 7] had speech problems so they used sign language when she was younger. They might be geared towards doing something for the deaf and h/h community. Your wife might enjoy listening to them. The wife is a knitter and spinner and the husband used to have a radio show and does voice overs for movie trailers and commercials. He is a non-knitter so it makes for a good listen.
