Men’s/Boy’s underwear. The “Y” refers to the y shaped seams where the fly is at.
Oh! You mean tighty-whiteys! 
thanks
Use WD-40 to remove the stick-ups. It will dissolve the glue nicely.
Stateside:
In the apartment in N.J. next to a wing of the “W” shaped building that had a fire and was being renovated when I moved in, a HUGE box of massive sponges in a closet with a snippy legend written with marker: “sponges the size of bricks used to clean up the awful mess from the fire!” and a stinky fridge- so incredibly stinky we had to make them give us another one!
Korea:
You wouldn’t believe how happy you are to live with someone’s bizarre cast offs when you have all of your things in storage and live in the 'ville “on the economy” as they say. In addition to the poisonously stinky Daewo we bought for two hundred dollars, we found in our apt: a set of really crummy ‘bachelor’ pots and pans, a convection oven and two gas burners that left huge licks of black soot on all pots and pans, the biggest, fanciest refrig I have ever had (complete with cunningly shaped ice cube trays and etc), two big ornate but somehow made of the cheapest sort of plastic and particle board wardrobes, and a lot of other strange and uncomfortable furniture (2 back-spasm sofas, a Korean bed-sort of a hard box spring/mattress combo with a futon on top)…lots of strange plastic medicine cabinets in the bathroom… We brought little to the country so we totally settled in with all of that strange found object shit and lived with it for an entire year! (even brought the step ladder home to the US and use it regularly in the kitchen!) I am a totally fastidious person and even I can’t believe it now that I’m all comfortable and sleek and in the West again.
A cow skull (filled with cement) in the back yard.
We’ve lived here 10 years and the landlord still has one unfinished bedroom crammed with antiques.
Surprising stuff has beed a logchain lost in the long grass.
Several coffee cans hidden in the floor joists in the basement.(no treasure though).
The neet stuff has been in the sheds outside.
Lots of tools. Lots of old iron We’re always finding parts of horse collars in the yard. But the most interesting thing was a half case of old dynamite.
