You guys, the red carpet for the 100th Episode (aka Season 5, Episode 11: “500 Years of Solitude”) celebration is the gift that keeps on giving. In a new video from ClevverTV, the Vampire Diaries cast is put to the test with a rousing game of “Who Said It” — and the fun that ensued is perhaps the most adorable four-and-a-half minutes you’ve ever seen.

Much to their chagrin, the cast was up for the challenge.

First up, Paul Wesley (Stefan Salvatore). The doozy of a quote Paul was given was: “I knew I couldn’t spike your drink, so I spiked hers.” While this automatically sounds like Damon Salvatore (Ian Somerhalder), Paul finally realizes it is Stefan after saying it in an over-the-top goofy voice. Come on, dude!

Nina Dobrev (Elena Gilbert), Kayla Ewell (Vicki Donovan), Ian, Matt Davis (Alaric Saltzman), Phoebe Tonkin (Hayley Marshall), Michael Trevino (Tyler Lockwood), Marguerite Macintyre (Sheriff Liz Forbes), Joseph Morgan (Klaus Mikaelson), and Steven R. McQueen (Jeremy Gilbert) all take part in the fun, with mixed outcomes. Clearly some people have some studying to do — we’re looking at you Phoebe!

Perhaps the most adorable segment, however, is when executive producer Julie Plec is put to the test. They gave her some really tough lines, but of course our favorite TV boss lady went two for two, proving that she is the TVD goddess we know she is. Runner-up for Most Adorable? That’s JoMo, of course! He really gets into the fun and is almost too excited.

Check out the video below for all the shenanigans!
