I'm ba-a-ack More Spanish, please

Okay, so I got a little sidetracked. Anyway, my wandering cat has now hooked up with a travelling circus, and one of the performers is teasing another about a perceived weight gain and she wants to return the "favor". How does she say "You should talk" or "look who's talking" in Spanish?

2. Now he almost trips over the cat, so how do you say "woops" or "oops" in Spanish?

3. How do you say "stay out from underfoot" in Spanish?

Thanks.

I tried that. All I got was a word-for-word literal translation for the first and last phrases, nothing at all for "oops". I'm looking for the idiomatic equivalent.

Thanks so much, Maxmordon. It's hard to know when the literal translation is right or will sound stupid.

Usually when people say this it means don't get in the way or don't bug me, but in this case, I'm wanting to say literally to stay away from the feet.
