I had something like that ..back in 1996 there was a song called "In the Meantime" that I liked and wanted to catch it on the radio (hey, it was 1996) I was reading a book and came across those words "In the meantime..." (I seem to recall it being a Mickey Spillane book for what it's worth) and so I thought I might as well check the radio and indeed it was on the radio, about 10 seconds in, which means it likely started when I'd read the words.
Another time after I'd seen Army of Darkness I was itching to use the line "Yeah...and I'll be a Chinese jet pilot!" (Ash says it at one point as a kind of "I'll be a monkey's uncle.")
I used to volunteer at my church's Sunday night bingo and there was one old woman that used to complain in light-hearted away about how she never won. I was ready with "Yeah, and I'll be a Chinese jet pilot" as my retort when I asked her if she thought she was going to win tonight......but once I asked her she if she thought she'd win she answered with "Pfft...Yeah right! And I'll fly to China!"
I nearly shit myself!
