I don't know too much about them either, but you made me laugh so much with your Q I had to find out for you!
Bum grapes, that's going to tickle me all day.
Jesus Christ, I looked and I am never going to strain again.
For the love of God, don't look at the photos on the 4th link .... hahaha try and resist.
Am going to be sick now, tada.
OO oww ouch,They burn,itch,bleed and really DO look like a bunch of grapes! I've had mine since having my 1st baby way back in the 70's. When they "POP OUT" I just shove em back up again. LOL.
when i was young my dad always used to bend over and ask me to pick the grapes and see if they tasted good. now i have read this i feel sick and will never look at my dad in the same way again.
