The Flying Eduardo Brothers (also known as Cirkus Eds) are a scam that appeared at the start of "Rent-a-Ed." In the scam, the Eds entertained the kids by putting on a circus act. Originally, none of the kids were entertained, largely because the Eds' act was rather boring. When Sarah voiced her displeasure, though, Ed stepped up his game and used his friends to perform an act that he had seen on TV. This entertained the kids up until Ed ended up breaking the playground's teeter-totter.
After Ed broke the teeter-totter, the kids all left, with Rolf throwing a hot dog at Eddy to show his displeasure. Despite none of them being pleased with the performance, no refunds were asked for (Eddy stated that they wouldn't get them anyway), which suggests that either the kids were willing to let the Eds keep the money and were somewhat entertained. Edd notes they had to use the money they earned to pay a repairman to fix the broken teeter-totter, but it is unknown if they did this since Eddy immediately started another scam. Later, the "Flying Eduardo Brothers" showed up again, when the Eds needed to escape the kids wrath.
