Fun with Bacon is an iCarly segment that appeared only in iWant a World Record. It was never actually shown, as they started the segment just as construction workers interrupted the segment to clean up the webshow room, filled with zenite gas that came from Freddie's light bulb.
The only hint of the segment is that we see Carly and Sam holding up bacon that is dressed up. It was probably created to fill the time while they were doing their day long webcast to break a world record. The segment was shown in the series finale, "IGoodbye", during flashbacks.
