ENVELOPE MISHAP OF '87

It's a little-known fact that in 1987, a catastrophic envelope-related incident occurred.

A batch of letters, bound for the local post office, were somehow mistaken for a batch of rare, exotic seeds.

The envelopes were sent to the local botanical garden, where they were planted in the soil and... well, let's just say the consequences were dire.

As you can see, the envelopes sprouted into a thorny, impenetrable shrub that still haunts the dreams of local postal workers.
