Running Gags

[Cat]

My favorite running gag was in SS/PS when Hagrid kept spilling the 
beans about stuff and catching himself too late and uttering the 
line "Shouldn't have tol' ya that."

OH and the fact that they FINALLY had the twins uttering the same 
lines in sync. I have known several sets of twins and especially when 
they were younger, they would say the same thing at the same time.

What running gag did you find humourous, distracting or annoying?
