At a 2006 outside broadcast at Oak Park Aquatic Centre for the SYN Pool Party series, Patrick Blampied - known at the time as Shifty - went down the waterslide (the tube-and-running-water kind) with a microphone. 
At the start of this clip you'll hear a vintage bit of announcing from Dan Hill, now working at The Fox in Melbourne.
My first contribution to the piece is telling Patrick not to do it, so you can hear I haven't really changed that much. 
At the time of broadcast, I was 16.
The picture attached is from the following outside broadcast, when a hailstorm hit and lightning struck about ten metres from our broadcast tent, and is provided by Mark "Squinty" Leonard, now at Coast Live.
