I am sure there are little pixies who come into my room and night and put more clothes into my already overflowing laundry hamper. I remember not putting them there.
Also, I cannot be bothered to wash said clothes, not even with the incentive of being able to iron them afterwards (ironing of course being the best thing in the world ever EVER). Thussly, I have no pants. Short-term solution: Go and buy more pants. Long-term problem: More washing of said pants.
Oh how I loathe my bouts of muppetry.
