This fast food franchise may also be linked to the television channel TBS, suspected to stand for Taco Bell Syndrome. This is, however, unconfirmed.

Jeremiah: You want tuberculosis??
Richard: Nah, Taco Bell, man!
Kimberly: I wonder what's on Taco Bell Syndrome tonight...
Brenda: That's a great question. I hear their shows are very funny.
