Dwayne Douglas Johnson (born May 2, 1972) is an American actor, former football player and professional wrestler. He is also known by his former ring name The Rock and is often credited as Dwayne "The Rock" Johnson.
The Rock appears in an Instagram selfie with Avery Bullock when Hayley flips through her phone in "The Long March". Bullock has tagged the picture as 'Twinsies!'
In "The Chilly Thrillies", when he eats pickles, Roger believes he sounds like 'Dwayne Vin Diesel "The Rock" Johnson', mixing both Vin Diesel and Dwayne "The Rock" Johnson.
When Hayley and Jeff recover a wheel from a crashed Lamborghini, Roger tags along to laugh at them using it to gain access to the exclusive Club Ataxia in "Frantastic Voyage". However, their club night is interrupted when The Rock invites them to ride in his helicopter to watch boxing in Atlantic City.
