My favorite joke

As told to me by a cute ESL boy last Thursday:

"I have a joke for you."
"Ok, tell me"
"I want to tell you a joke."
"Please, I'd love to hear it."
"OK. Why six scared seven. Hehehehehe."
"Oh, I love this joke!!! It's my favorite! -Because seven, eight, nine! Hahahahaha."
"You get it? Seven, ate (making food towards mouth gestures), eight - the number, nine. Six, Seven, Nine, Eight. You get it?"
"Yes and that is my favorite joke in the whole world and I'm glad you get it."
"It's so funny."
"Yes, yes it is."
