Well.. How many times haven't this happened me
All your stories reminds me of similar situations where i get the blame for everything even tho i did nothing...
Tho it doesn't happen too often nowdays, but theres a similar things that makes me really angry: My brother can't keep any secrets i tell him...example: Me and my freind talks about something secret on the phone, my brother hears something of it and asks what i mean with that, i say no, then mom/dad goes something like..you know.. "Can't you tell him Timmy? Bla bla bla" it's so annoying sometimes...
Another thing is when he asks me for help on some boring videogame... Then if i say no, my parents just nags me...
But i think the worst is when he always has to spoil it everytime i try to suprise someone...example: me and my family is in shopping for new clothes or somthing, i see my freind while walking between the stores, then my brother sees me while trying to sneak up behind my freind and suprise him, i point at him to be quiet.. then.. the second before i'm behind my freind, he does something stupid and spoils everything :'(
