Finally, a place to document your finest emissions. A Tiny Fart Diary by Brass Monkey turns a passing moment into a permanent record, with space to date, rate and evaluate your latest contribution to the atmosphere.

With 112 pages, a foil-stamped felt cover and gold-edged pages, this miniature diary gives a ridiculous subject a surprisingly fancy home. Keep it handy for noteworthy incidents or give it to the person who already provides the commentary.

Small enough to tuck into a stocking or gift bag, it’s a cheeky choice for gift exchanges and anyone whose sense of humour hasn’t entirely grown up.
