The 2018-2019 TV season has come to a close, but we can't let our favorite shows take a hard-earned summer vacation without paying our respects. And while we've got plenty to say about the best and buzziest moments of the year, it's only right to let these characters speak for themselves.

So in addition to scribbling Have a great summer and You rock, never change in everyone's yearbooks, we've also rounded up the year's most definitive quotes — senior quotes, if you will. Some are memorable sign-offs from the characters who left us, like The Walking Dead's Rick Grimes (Andrew Lincoln). Others are perfect introductions to new arrivals, like Sex Education's Jean Milburn (Gillian Anderson). We're also throwing it back to laugh-out-loud jokes from class clowns like Moira Rose (Catherine O'Hara) on Schitt's Creek, swoon-worthy declarations from lovebirds like Alec Lightwood (Matthew Daddario) on Shadowhunters, and deadpan comments from outsiders like Jughead Jones (Cole Sprouse) on Riverdale. And we couldn't forget about the queen of the withering insults, Game of Thrones' Cersei Lannister (Lena Headey).

This television season delivered some unforgettable lines in every genre, from comedy to drama to reality TV. Did your favorite one-liners make the cut? Check out the gallery below, and don't miss the rest of TV Guide's TV Yearbook coverage.
