I've got a couple of examples, for our 20th wedding anniversary my husband bought me a toilet brush (admittedly it was one that I'd been seeking for a while, but really!).
Many years ago I was in hospital (gallstones) and my get well gift was a massive book of 1001 recipe ideas, I tried not to take offence but once again....really?
Would love to hear of anyone else's gift fails.
Lighthearted.
