I love this kind of stuff

A lexicographer discusses words we intentionally say incorrectly.

via Kottke.

Any additions I thought of were listed in the comments. I say shomp-ang-ya for champagne, tar-jay for Target, gar-baj for garbage... I've definitely used internets, interweb, etc (thanks to living with Jon and Josh). Vino instead of wine. Etc.

An old boyfriend had one ex who said pitcher instead of picture, and another who said lellow instead of yellow. I'd tease about that every once in awhile.

Then there's stuff like saying a'ight instead of alright (I remember an old SNL sketch that I picked up on this from, but now it's really common as well).
