 In the original broadcast of the season 2 episode "Kryten", Rimmer, when  confronted with the dead crew of the Nova 5 says "Theyve got less meat on  them than a Chicken McNugget".  MacDonalds took exception to this and  threatened legal action.  All subsequent broadcasts and releases had the "Mc"  of "McNugget" silenced, though Rimmers mouth still forms the full word.
