Dan Piraro's Edgar Allan Pooh Bizarro strip (partially thumbnailed here) brings some new light to the relationships in the Hundred Acre Wood. Piraro explains,
The truth is that something very similar to this cartoon actually happened in A. A. Milne's original manuscript for The House at Pooh Corner in 1928. Pooh was quite naturally creeped out by Eeyore's nailed-on tail and becomes obsessed with it. In a fit of hyperactivity brought on by a weekend honey binge, Pooh caves in Eeyore's head with the honey jar and buries him beneath the floorboards.
