* "PFFT! You Was Gone!" : A comedic duet featured on the premiere episode and holds firm as one of the series' most endearing sketches. In early seasons, the song was performed by Campbell and Tapp (both with solemn looks on their faces), in the vein of folk songs like "Oh! Susanna" and "Old Dan Tucker." In later seasons, Tapp would be increasingly replaced by that episode's guest singer, or another surprise celebrity (normally if it were a guest, his or her name would be included in the lyrics of the song before they would sing the refrain). Tapp, or whoever it was, would often stand with their back to the viewer while Campbell sang the new, humorous verse solo, holding a scythe. At the end of the verse, Campbell would elbow Tapp or the guest (as a comedic visual cue), who would then spin around (Tapp would react as if awoken by the elbow) to join him on the chorus:

"Where, oh where, are you tonight?
Why did you leave me here all alone?
I searched the world over, and I thought I'd found true love,
You met another, and PFFT! You was gone!"

The "PFFT" would be done as a spitting "Bronx cheer", and occasionally, they would break up into laughter after the "PFFT", unable to finish the song (Who got spat upon during the "PFFT" would change each show.) Following Campbell's death, whole groups and even women would be part of the refrain, with future regular George Lindsay often singing the first verse. Occasionally, in the later years, Roni Stoneman (in her role as Ida Lee Nagger) would sometimes do the first verse. In some episodes, which had several major guest stars, the routine appeared several times in the show so that each guest would have the chance to be part of this tradition.

thanks if you can help
