Grapes of Laugh

Lili and I went out to lunch today for Mexican food, and then grabbed some Mexican pastries and brought them back to lab.

Me: So, do you have Mexican food in China?
Lili: No, we do not
Me: How about American food?
Lili: Just the chains. We have McDonalds, and the Ken...tur...key?
Me: What?
Lili: Kenturkey? The chicken place?
Me: Oh! Kentucky Fried Chicken!

Back at lab, we're eating our pastries, and the CSA grapes I brought in.

Bob: I have a joke. How many graduate students does it take to change a light bulb?
Me: Hmmm...
Lili: Change...a...what?
Bob: Do you know that kind of joke?
Lili: Lightbulb?
Bob: It's a type of joke to make fun of people.
Lili: I don't know change lightbulb
Bob: Ok, well, the answer is, just one, but it takes 7 years and at the end they don't know why they changed it.

Me: Who wants some grapes?
Bob: Oooh! These are concord grapes! I love these!
Lili: Con...crete?
Me: No. Concord grape. It's a type of grape.
Lili: That is the word...when I go to the airport they have A and B and C?
Bob: No, that's concourse. This is just concord, a type of grape.
Lili: Oh! Ok! hehehehehehehe.
