Give me a moment to think of the right joke...

Mergers proposed for schools for blind and deaf

Why not go for the trifecta and add speechless people for a school of the blind, deaf, and dumb? (That is not the right joke.)

It reminds me that my elementary school had a special program for deaf, hearing-impaired and partially sighted students. I can still tell by a person's voice whether they are hearing-impaired though I was never able to absorb any of the sign laguage lessons they gave us.
