Mr. Wyland was the 3rd grade substitute teacher for Mr. Garrison in two episodes after Mr. Garrison was caught attempting to molest a child, Eric Cartman, in "Cartman Joins NAMBLA". He was first shown in "Cherokee Hair Tampons", where he made the class make a get well card for Kyle, who had kidney failure. He also appears in "Chef Goes Nanners" to have the children debate over the South Park Flag.
Wyland wears a blue jacket, similar to Randy Marsh's, with a red bow tie. He has a double chin, wrinkles on his forehead and brown hair.
