This is a short 2.5-second spoken line from the Portuguese version of Aqua Teen Hunger Force, taken from the Christmas ghost episode. The delivery is odd and abrupt, which makes it land as a strange, funny interruption rather than a normal line of dialogue. It comes from Fantasma do Natal Passado, where the ghostly Christmas visit turns into something unexpectedly silly.
