You can choose from a dare below, and I will perform it and send you evidence once the money is received. Or you can come up with your own dare! We will have to agree on a price before I follow through though...

• Find 10 strangers in the street in 1 hr who will allow me to draw faces on their belly (navel=mouth) (£50)

• Walk into Gucci store and ask for a coat that matches my dog, showing them a picture/borrowing a friend's pug (£40)

For truth: negotiable, but I can give you the answer to your burning questions for donations of £5 upwards, in private.

I worked for Tacugama Chimpanzee Sanctuary myself in 2012-15 and have seen with my own eyes how they do important work on a shoestring budget. Really wanted to help raise some much needed cash for them in a fun way and hope you will participate! http://www.tacugama.com
