The seventh comic: #973 Masterpiece Comics
Unfortunately this feels like a comic we read a bit too early - one of the few cases where I can truly say that. Combining a comic (or comic style) with a famous work on literature - books and plays - it goes through the Bible, Dante's Inferno, Wuthering Heights and more, while using the stylings of, amongst others, Garfield, Batman (and other superhero cartoons) and Little Lulu. I got most of the references, but some are a bit too far removed to really always make sense.
The stories aren't necessarily funny (unless the comics link into it) but the juxtaposition often adds to making it more amusing, and it's what makes reading these comics so special. A very good read.
