Bit of Translation Help

[ch0b1ts]

In my current Japanese class, we have to translate a scene from "Meet the Yamadas".
Having only completed 13 Credits worth of Japanese classes, it is quite a challenge to come up with a translation. I need just a bit of help with the following.

一番：禁パチ日
I know the meanings of the first and last Kanji; however, I'm having trouble coming up with a translation for the whole thing. From the context of the anime scene, I'm thinking that パチ may be short of パチンコ but I'm not sure.

二番：かっていてくれ
The hint my sensei gave us on this one is that it is made up of the following
かっておく
くれる

三番：行っちゃった

ありがとうございます。

Ok I figured out the 2nd one.

The line from the anime was as follows.
たばこ、かっといてくれ。

て form + おく
to do for some future purpose

くれる
to give (giving and receiving). Don't cover this until JPN298 (Next Summer).

So a rough translation would be. "buy me some tobacco later"

You're right, it is short for Pachinko. It's always a little difficult without knowing the story but I'd translate it as "No Pachinko Day".

三番：行っちゃった

As you probably know, this is made up of 行く and しまう = 行ってしまった　= 行っちゃった.
You could translate it as "They've already gone."

しまう was the missing piece I needed. 〜て＋しまう　
where ちゃう and じゃう are the abbreviated forms.

I always enjoy learning new sentence patterns.
