Here in the north of Italy people thinks that only exists one park: Gardaland. 
  
Some I heard: 
  
"Why is the Blu Tornado green?" (standing in front of Magic Mountain) 
"What if they fall down?" (referred to the Screaming Squirrel) 
"Is that a real volcano?" (Jungle Rapids)" 
"They're removing a train from the track! They want the queue to be longer!"    
"You don't go upside down, the seats does!"    (talking about a Mad House) 
  
At Mirabilandia: 
"Katun is the highest coaster in the world!" 
"I have never been to DisneyLand, but I know it sucks because there are not coasters!" 
  
But the best one in the world is this one. 
In Gardaland 'till last year there was a ride called Tunga: The Apeman 
I've heard a GP translating: "Tunga: l'uomo ape" which in English comes "Tunga: the bee man"   
  
EDIT: I pressed "submit to park index" without getting his function, sorry. Ignore it!
