Complete the Lyrics- My Chemical Romance Style!

Can you complete the lyrics to these MCR songs?
Believe me, if you know you're stuff you're gunna be wonderin why some of the answers are so stupid, not my fault. These are actual misheard lyrics that people have used in videos or lyrics sites.

Please don't critisize too much if its utter rubbish, im really bored and it's just for laughs, ok?
