Another one from Griffinesque: "Friends are like potatoes, if you eat them they die." I love the idea of Merlin being Arthur and Gwaine's first friend so they don't really have experience with friends before and therefore don't understand much about the concept.
"Admit it, princess," Gwaine slurred. "We're friends."
"Dunno, Gwaine," Arthur responded, his speech just as affected. "Dunno much 'bout havin'em. How'm I s'posed to know I got one?"
"Well," Gwaine began determinedly. "What I've learned 'bout friends… they're like potatoes."
"'Kay." Arthur swallowed, swaying slightly. "How?"
The room was loud; Gwaine hadn't heard him. The prince flicked his ear and, louder, asked, "How?"
Gwaine stared blankly at Arthur.
"Wot?"
"How're friends like potatoes?"
Gwaine blinked confusedly.
"…If you eat'em, they die?"
Arthur blinked, then clapped Gwaine on the back laughing loudly. Gwaine grinned and took another swig of his ale.
