reading the youtube comments on the laughing video someone is saying that it has happened 3 times in the comics. Doesn't mention which ones though.
"He defeated the Hulk about 3 times in the comics. The comics I've read at least."
"a) He teamed up with Spiderman who was a martial arts fan at the time. Spiderman told him about a move that was done with 5 hits to the legs, arms and finally chest and would slow the heart's beat, resulting in the Hulk being human again. Hawkeye was left with 4 arrows left,he successfully hit his targets,and Spidey delivered the final move by strongly punching Hulk's chest.b) He fired an arrow with an adamandium edge that contained the Hulk's cure even though he was shot in his shoulder before."
"c) He fired 6 arrows in a closed dark room that filled the room with gas also containing the Hulk's cure. Yes, a lot more complex than the previous but he didn't have an adamandium arrow back then."
