If you like pina coladas, you might also like walks in the rain

The cucumber vs pickles one is wrong. There's a chemical in cucumbers that something like 1 in 50 people can taste (it's also in watermelons, though at a much lower concentration) and if you can taste it, it's horrible. Anyhow, something in the pickling process neutralizes it or changes it or whatever, so that's why I absolutely despise cucumbers but am totally cool with pickles. It has nothing to do with liking vinegar.

Edit; a quick Google reveals that it's "due to the presence of toxins like Cucurbitacins and Tetracyclic Triterpenoids in cucumbers." Again, the vast majority of people can't taste it, but for those who can, the taste is God awful. I can't even really eat something a cucumber has touched.
