Bleeped editions on DVD?

Years ago at Best Buy I saw various box sets of the show on the shelf, not knowing what it was but seeing it had Penn & Teller on them.

Maybe I recall incorrectly but one or more of the DVD sets had certain characters, letters or symbols replacing the "I"...maybe it even said some thing like "Bleeped" on it.

The show doesn't have bleeped or censored DVD editions, does it?
