Like my anti hair wrap hoover..just literally had to cut hair off the roller bit..i could of made a wig out of the hair i pulled off it!
Also superglue..the only thing it seems to stick together are my fingers
And cordless hoovers
Not going to mention paper straws
Any others to add?

Those hooks you get for the bathroom, with the suction pads to stick them to the tiles ....................... for about 3 minutes. So you scrub the tiles and stick them back on ................................ And then you get the white spirit from the shed to get the tiles really, really clean and you stick them back on ...................................................... and then throw them away.

I got some shelves from Amazon that stick up with those, fully expecting them to be shit
They're still up, and not budging despite the hefty amount of crap in them
