My Dad is a Technologist and is a very good speaker, and his only advice for tonight was start with a joke, so here goes.. You Might be an Technologist If... ... the only jokes you receive are through e-mail. ... you can't write unless the paper has both horizontal and vertical lines. ... a team of you and your co-workers have set out to modify the antenna on the radio in your work area for better reception. ... Dilbert is your hero. ... everyone else on the Alaskan cruise is on deck peering at the scenery and you are still on a personal tour of the engine room. ... people groan at the party when you pick out the music. ... the blinking 12:00 on someone's VCR draws you like a tractor beam to fix it. ... the salespeople at Future Shop can't answer any of your questions. ... you are always late to meetings. 2006 Building Code - Overview
