Dialog 1 a knee-jerk reaction [ 自然な反応 ]

Yukio:I was really surprised last night when I walked into a bar.
Alicia:What happened?
Yukio:The bartender was Caucasian, so my knee-jerk reaction was to speak English to him.
Alicia:Oh, so he didn't speak English?
Yukio:No. He grew up in Japan and could only speak Japanese.

Dialog 2 everything but the kitchen sink [ なんでもかんでも ]

Alicia:Alright, I'm ready. Let's go to the baseball game.
Yukio:Hey, you're taking everything but the kitchen sink!
Alicia:I might need all these things!
Yukio:Let's see, a seat cushion, a parasol, a baseball glove, a portable TV, a bullhorn, and a vanity mirror. Hmmmmm.....I doubt it.
