You want to make sure your friend has a festive birthday.  Show them you care by offering this invaluable advice.

When my wife saw the design for this card, she noticed that the drawing was from the first person's point of view and asked what I used as a reference to draw it.  All I said is that I had to draw it with my left hand.

Imagine their face when they open it

Will they be surprised? Impressed? Offended? Will they giggle and drop a bit of wee into their pants.

Will they get a glimpse of what you're really like?

I hope so, you should be proud of how naughty you can be.

We get it

Every day you have to behave yourself and do all of the stupid crap that society expects you to.

You have to wear the right clothes, keep your job, be polite, try not to wave your important parts around in public, and remember not to say naughty words or offend anyone.

Be kind to yourself and give yourself a break, release some pressure and do something bad.

You owe it to yourself, and to your friends.  They’ll love you more for it, I can promise you that.

With so many of us suffering from anxiety and depression, we need a way out, an escape, a way to break through the stupid social norms.

Our aim at Mr. Inappropriate is to give you a break from all that, be yourself, and have a laugh.

My name is Dan, I’m the founder of Mr. Inappropriate and I firmly believe that we’re not designed to live like this.

We haven’t changed much since the time when we ran around with a spear chasing something to fuck or eat, or escaping from someone else doing that.

And now, we have to deal with emails, debt, job and a million other things, not to mention the fact we’re not allowed to express ourselves anymore for fear of offending someone.

If you’re feeling stressed and anxious it’s hardly surprising.  

Let us help by giving you a moment to escape, have a giggle and not give a shit.

And help your friends do the same!

  • Custom card message and send it directly to your recipient.

  • Cards/candles: buy one get one 50% off.

  • All designs are hand drawn in our home office near Leeds.

Very pleased with my order!

I’m very pleased with my order. It arrived quickly & was packaged securely with a card enclosed inside the envelope to prevent it from being damaged in the post. I was kept well informed of my order via email from the moment the order was placed until I received it. The recipient of the card appreciated it & saw the funny side! I’d recommend Mr Inappropriate & will order from him again in the future as there is a wide range of products on the website. 👍🏻

Thank you so much for saying all that Richard, really kind of you as it really helps others get a good idea what it's like to order. Thank you!!
