Funnyisms

My kids are nothing if not funny! Here are some recent conversations:

In the car on the way to school:
Annah: Liam you are not a big boy, you are a baby
Liam: I is a big boy Annah!
this goes back and forth for a while :) until Liam clinches it with this
Liam: I IS a big boy 'cause I tee-tee in the potty and I poopy in the pantry!

Annah after getting dressed this morning, takes a look at herself in the mirror and says "mommy, this skirt is a good look for me!"

Liam and I went to the park one morning while Annah was at school. There is a fire hydrant right by the entrance to the park and a fire hose was left (unattached) right next to it
Liam: Mommy, I want to take that hose home with us
Me: Oh Liam, that is too heavy for you to get it in the car
Liam: Mommy, you are very strong (long pause)...why don't YOU put it in the car for me?!

Liam was playing with his grill this afternoon and it has wooden pieces that go with it. One of the pieces is a ketchup bottle. The top (obviously) does not come off the bottle. Liam comes over and says, "The problem is the top won't come off...that'll be $50!" It wouldn't be so funny, but it sounds like something someone in the service department might say (ie the problem is your car is out of gas...that'll be $300)

Finally, the cream of the crop. Liam and Annah are both in the tub one day last week. I look at Liam and he has 4 very clear fingernail scratch lines going from the top of his chest all the way down his belly. So I ask Annah what happened:
Annah: It was an accident!
Me: No way that was an accident. You had to mean to hurt him to do that.
Annah: No Mommy. I was trying to hit him, but I accidentally scratched him!
How can I argue with this kind of logic?!
