Chong, ch-chong, chong chong

The story:

My mother was the one who had the unfortunate experience of misinterpreting the song. She had asked me why they made up a song about Cheech and Chong. I was confused, so she said, "Ya know, Chong, ch-chong chong chong." I nearly died laughing at the poor woman, and then had to explain to her what the words were.... underwear, not sandals. She was then horrified and wanted to know why someone would make up a song about underwear!
