Gutted, missed the first round! That's what I get for playing Skyrim.
Round 2A. Bart Simpson & Lisa Simpson
B. Captain Kirk & Spock
C. Hairy Snotter & Hermoine Grainger (I don't know who the other ones are)
D. Han Solo & Princess Leia
With commentary
A. Bart Simpson & Lisa Simpson
A. Batman & The Joker
I am not sure if we even have a rapscallion who needs stopping by a knight errant, but it is better than Dumb Brother and Smart Sister.
B. Captain Kirk & Spock
B. Frodo Baggins & Samwise Gamgee
Frodo is a whiner with hallucinations and Sam is dear dependable punching-bag Sam, which is a way cooler dynamic than Stupid Brave and Smart Deadpan.
C. Harry Potter & Hermoine Granger
C. Jon Stewart & Stephen Colbert
Not too keen on Harry Potter for the Ciddies, but what is the alternative? Funny and Almost as Funny?
D. Han Solo & Princess Leia
D. Sherlock Holmes & Dr. Watson
Because they are the cutest gay bickering couple ever. I think all Han and Leia say to each other is "smurf you".
