Funnily enough, I just emailed them yesterday!
This was their response
Dear Hairylegs47,
Thank you for your recent correspondence pertaining to our stock.
Our male and female product designers create certain t-shirt ranges that are fun to wear and their intention would never be to cause upset or offend our customers.
Please accept our apology for any upset these garments may have caused you.
Yours sincerely,
Yeah, they are really sorry 
They remind me of those peanuts on a board in the 70's. Didn't think pictures like this had a place in the 21 century on tee shirts any way.
Signed
