Peas, Please

On our way to Logan's first day of preschool/MDO this morning, the Black Eyed Peas song "Tonight's Gonna Be a Good Night" came on.

Logan: Mommy, what kind of song is this?
Me: It's by the Black Eyed Peas. Why? Do you like it?
Logan: No. I only like green peas.

Then at dinner tonight, he was picking at his peas (which he usually devours):

Logan: Is there pee mixed in my peas?
At first I didn't understand him so he pointed "down there" to clue me in.
Me: No. And we don't talk about that at the dinner table.

He's very big into talking about his penis and pee (although I always call it tee-tee with him, not sure why he says pee--wait, it's because I say pee...oops). We were at Wal-Mart the other day and walking past the deli counter, as clear as day:

Logan: Are we going to get a penis?
Me: No. And we don't talk about that at the store. You're too loud. (as I am trying not to laugh)
Logan: But why? (laughing hysterically)
Me: (I got nothing) Let's go see if we can find the applesauce.

What am I going to do with this child? It's so hard not to crack up laughing but I also know that it's not always appropriate for him to talk this way. Not to mention that he is becoming a full-on boy, tooting and burping, or pretending to toot and burp, and laughing like crazy. I KNOW he'll never grow out of that.
