I Was Laughing Uncontrollably

Yesterday I went over to Tuli's apt, 6E, and I brought with me my cutting board, my knife and some fruit. Tuli, Ruthie and myself were eating peaches and avacodos. Shoin. Then, afterwards, I went to the kitchen to wash off the cutting board and knife.
In the kitchen, Moshe Lorenzo saw me and commented: "Wow, that looks like a nice knife."

"Naa, actually it stinks."

"Oh. Well I bet it was really good when you bought it."

"Actually, I just bought it a week ago."

"Why don't you get one of those rocks to sharpen it with?"

"I have one, it didn't do anything."

By then, I was laughing uncontrollably, and Moshe Lorenzo admitted that he could not help me.

[Btw, the Rapps' own the knife in the above picture. That one happens to be an excellent knife.]
