On the way to Moscow en route to Yerevan

Sitting on the runway
And suddenly
Toenails that had never been clipped
Bc they had the color of dead people's
Toenails
Were sitting at my elbows
They came with feet that had black and gray
Stuff, toe jam, cotton or just floor crap picked up
By bare feet
Sprinkled all about
I didn't see these alien extremities
They were brought to my attention
By their smell
Where I started looking around
And found nothing
Until I looked down
The culprit
Was there
And I wondered
Was foot cleaning customary
In russia?
