It's not actually teaching what happens in the Thymus and bone marrow, to be honest. When a T-cell is generated, certain sections of its DNA are mutated so that it can respond to foreign proteins.
However, the process of mutation is inherently random. What the 'teaching' in the thymus and bone marrow do is that if these cells do not respond to foreign antigens, or if they respond to the body's own antigens, the T-Cell is killed.
EDIT: Damn. Sarnath'ed.
