Same thing happened to me a couple years back in freshman year!!! Well first off, just don't tell your mom. When you start getting fat from the baby bump, just say you've just been eating a lot of junk food. Start wearing baggy clothes to conceal it too. Also when you have it and put it in the jar, make sure you poke some holes in the lid, Wouldn't want to be throwing a dead baby now would you!? Some good advice, before you go to throw the baby, cover your licence plate number so he can't report you. Then just wait until he posts on his twitter "Who the **** just threw a baby at me??" and be satisfied.

Well that's all I've got! Hope I helped!!
