Matthew, Mark, Luke and John, see me after class. Your book reports are surprisingly similar.
James McGrath shared this humorous cartoon which depicts the rather uncomfortable position in which the four Gospel authors would be had their papers been flagged by a teacher for copying from one another.
Mark Goodacre points out, however, that there are couple of problems with the cartoon.
1) The presence of Jesus in the classroom who would not have been around when the Gospels were written.
2) Few would find John's Gospel to be similar to the other three.
Nonetheless it is a funny depiction of the Synoptic Problem. You can find more such cartoons at the Young Jesus Chronicles.
