I lived in the McMahon Hall dorms at the University of Washington
from 1980-1984 while getting my undergraduate engineering degree.
I was (randomly) paired with a roommate when I started and was
very fortunate to get Jim Oliver, and we got along well.
Jim didn't stay in the dorms the entire time, but we had fun
with various hijinks over the years. While we never really did
anything "bad", some of the stunts that come to mind were:
The Coppertone Girl
Funnelating water balloons (and other items) at other dorms
Various shin-digs (the infamous "cocktail hour" and the s*it-kicking county parties)
Charter bus ski trips
Many others I've forgotten and/or will research/recall at a later date
Jim had done gymnastics in High School, so he would do various "tricks"
such as while standing, do a back-flip and end up back on his feet.
Years later, we climbing a Colorado 14'er, and he even did one there.
As a footnote, I climbed
Longs Peak, Colorado on my 40th birthday.
Another impressive thing was handstands ... not just "normal" handstands,
but handstands on the balcony railing of our dorm cluster - 7 stories up!
Sorry, no satellite photos of this - only the pictures below.
Jim claimed if he ever felt unstable, he would push himself back toward
the balcony - he did this numerous times and it never got "dicey" - but
it's a long way down, so needless to say, this activity is NOT recommended.
