My friends and I used to “spontaneously spoonerize” when I was a kid. One day when we were playing frisbee outside I said to them “I have to go shake a tit”. I’ll always remember that one.
My sister and I now call the Jazz and Blues Federation the Blahs and Jews Federation all the time after one of us spoonerized it the first time.
I actually used the phrase “cunning stunts” in a book, just to make my friends laugh.
My mother was doing her spring cleaning a couple of years back and wanted to get her rugs and drapes professionally cleaned. I was in the next room when I heard her call a service on the phone and clearly ask, “do you do drugs and rapes?”
We both fell on the floor for a good half-hour.
I get up every morning and “shake a tower”
Hm, Bean, that one sounds like it belongs in the double entendre thread. 
Shirley Bassey is my favourite.
On behalf of nannies everywhere, I would just like to voice my strenuous objection to the proliferation of this spoonerism. This reprehensible association of child-care professionals with criminals must be eliminated in one swell foop.

Hm. There’s also a hamburger restaurant that my sister and I always had to be careful when naming, as otherwise it would come out very wrong.
Fuddruckers.
my favorite bumper sticker and one of my favorite phrases:
“I’m going nuckin’ futs!”
I don’t even try anymore, I just call the damn place “Buttfuckers”.
