Have you ever come across any DMs or players with weird speech disorders or accents?

A recent DM I've been playing under is mostly fine when he talks, except that whenever he says a word that starts in "sha," he kludges it up into "ta."

I have to restrain myself from giggling like a little girl whenever I hear priceless pronunciations like: tadow (shadow), Tadowfell (Shadowfell), tade (shade), tarp (sharp), tard (shard), TARDMIND (shardmind), tape (shape), and taman (shaman).
