English teacher's attempt in making a joke.
Teacher: Yes, they [humanists] were bringing Greco-Roman back.

Teacher: Yeah, I also heard that the original song title was going to be Greco-RomanBack, but his producers wouldn't let him, so he settled for SexyBack.

Student: Oooh! I get it! It's a Justin Timberlake's song!
Class: Ooooh. . .
