Lions, tigers and clams?

One thing I didn't expect didn't expect with parenting is some of the odd middle of the night conversations I might be having. John has been waking up lately in the wee hours of the morning with irrational fears - apparently not extraordinary. They typically range from a man out of his window, to Santa Claus, to aliens - not sure where he picks up some of this stuff as we've not seen Dora or Blues talking much of aliens these days. Anyway, though I'm not sure if it definitely falls into the irrational fear category or half-dream/half-awake category, last night was particularly odd I thought. I walk into his room and he's sitting up in straight in his bed and looks at me immediately and declares:

"Daddy, I don't *like* crayams!";
Me: "Huh, you don't like crayons?"
John: "Daddy, I don't like *crayams*!"
Me: "Oh, you don't like (I had another guess last night but don't remember what it was now;)"
John: "Daddy, I don't like *crayams*!"
Me: [fully aware this was my last opportunity to guess before melt-down] "Oh, okay buddy, you don't like clams."
John: [calmer now] "Yes Daddy, I don't like clams"
Me: "That's okay, buddy, I don't like clams either. As a matter of fact, I don't think thing Grace or Mommy like clams either."
John: "Daddy, let's leave the clams at the clam store."
Me: "Um... ok buddy, no problem, we'll leave them at the clam store."
John: "Ok daddy."
Me: "Ok, let's get back to sleepy time."
John: [rolls over]
Me: "Sweet dreams"
John: "Sweet dreams daddy"

There was really more to the dialog than this but I can't remember it in full. It was odd to be talking about clams at 2 in the morning with a 2 year old though.
