Despite the title of the episode, at no point does the PTA (Parent-Teacher Association) actually disband. The title was suggested by David Mirkin and was intended to poke fun at Jennifer Crittenden, who thought the most exciting part of the teachers going on strike would be that the PTA might disband. In addition to this, Mirkin added a character to the episode who, on thinking the PTA has disbanded, jumps panicking out of a window. He jumps back in the same window when he is told the PTA has not disbanded.
The section of band's class playing 'God Save The Queen' (the United Kingdom's national anthem) and 'Pop Goes the Weasel' was later taken out of repeated airings.
In the opening shot of the episode, the bus that the children travel in to the field trip had to vibrate up and down to give the impression that it did not have bumpers and that it was falling apart. Swinton O. Scott III said it was difficult to animate the scene because of the vibrating and the backgrounds panning.
