strange words

I was in ulpan class the first time I heard the Hebrew word for traffic jam. P'kak. I couldn't stop laughing. I got a few strange looks from classmates but I couldn't stop giggling. The word sounds like the sound an animal would make when stepped on, not a traffic jam! Now, over a year later I still find it funny to say P'kak. Instead I just use the plural form, P'kakim, this way I don't burst out laughing. The other weird word is ritch ratch (zipper) Ritch ratch coupled with the way Israelis pronounce their R's, makes the word sound like someone's growling at you.
Once when I was trying to get some information from my bank, I was told to call the other sniff. Call the other what?? I asked. The other sniff she said. I didn't understand what she was trying to tell me so I thanked her and hung up the phone. "The woman on the phone said I need to call the other sniff," I said to my husband. "What is that??" My husband couldn't stop laughing. Sniff is the Hebrew word for branch. Gee...they couldn't pick another word? it had to be sniff? how weird!!
The word knock, as in someone is knocking on the door, sounds like a dirty word. Knock in Hebrew is Dafak. Hearing the phrase Mishehu dafak al ha delet (Someone's knocking on the door) always makes me grin.
The other thing that makes me laugh is seeing English words spelled in Hebrew. It just LOOKS funny. Sometimes I look at a word and I have to say it a few times in my head before I realize that it's an English word written in Hebrew=)
