Worst Gifts:

Diet cookbook - Nobody wants to be subtly told they need to lose weight.

Half eaten box of chocolates - Just shows your gift was totally forgotten about and lacks effort.

Relationship/Advice books - Men are from Mars, Women are from Venus -

Candy bra / edible underwear - Is simply tacky and nobody benefits from these items.

"Diamond ring" Keychain in a box - Gives so many wrong signals. You want to show you're committed but lack the final touch.

Random food gifts - Unless it's a luxurious hamper, there is no need to give ready meals.

Holiday themed hand towels - They can only be used certain times of the year and are therefore, pointless.

Gift Voucher for a wax - Would you like to be told that you need a little hair removal treatment?

Socks - Seems to be everyone's last minute gift but we can all buy our own when necessary.

Bathroom Scales - Household appliances, especially bathroom scales are never really a thoughtful gift.
