that same thing happen to me but with my lazy boy
back in "82 it was a Sunday or maybe a Monday??
I was just sitting in it one night and it just exploded!

My first thought was a sniper too! (we get alot of those here!) Theres alot of trees behind me that a sniper could possibly hide...but I was indoors (are there indoor snipers?)

I guess these are just life's unexplined mysteries that we may never know...
keep smok'n ,
