I brought these cards last year as a secret santa present. I brought them for £5.00 in Hawkin's Bazaar. I believe they're also available for around the same price at Amazon, Paperchase and some other retailers. The cards are made by a company called 'Jam' who also have other cards available, including Minger Power cards!
The cards come packaged on cardboard backing with plastic over the top and there are a fair amount of cards per pack (about 20). Unfortunately they don't come in a box or have a case to keep the cards stored away (most playing cards and Top Trump style cards tend to come with a box or case).
On each card is a real photo of a real person sporting an epic mullet on top of their head! Underneath is written 'Special skill', 'Style', 'Odour', 'Strength in length' and 'Mullet Power' with different things written next to them, some rather rude and some a little vulgar... but mainly just amusing! Here's some nicer examples:
Special Skills - Chatroom Wooing
Style - Chuckle Brother Elite
Odour - Family Bucket
Next to each 'skill' is a number, so the cards can be played like a game of Top Trumps. If you're unaware of Top Trumps, here are the rules. You split the cards equally between players and make sure your opponent doesn't see your cards. Players take turns to choose a skill to play by, whoever has the highest skill number wins the opponents card (Eg. Strength in length 7 would beat Strength in length 4). The winner is the player who wins all of the cards.
The Mullet Power Cards are jam packed full of some awful (or brilliant, depending on how you look at it) mullets and gave everyone a good laugh at Christmas. The recipient was very pleased with their cards and others even tried to swap with them! These cards won't be everybody's cup of tea but I'm sure most people with a light hearted and rather silly sense of humour will appreciate them. I don't feel bad about laughing at somebody else's expense simply because I'm laughing at their hair, which they chose to style in a ridiculous way! I think some of the other cards (such as Minger Power cards) can be quite cruel. I prefer to laugh at somebody's silly haircut, rather than those who have an unfortunate face (you can change your hair but you can't change your face!). Not only are the mullets excellent but the game is surprisingly enjoyable too!
I recommend these cards as a fun, light-hearted, novelty gift for those who are easily pleased by bad haircuts!
