Kudos to Matt McGee whose Top 21 Signs You Need a Break from SEO gave me a few hearty guffaws. A couple of my personal favorites:

• When your son tells you he wants to go play in the sandbox you fear you won’t see him again for eight months.
• You feel uncomfortable and out of place at a minor league baseball game because you don’t see a Text Link Ads advertisement on the outfield wall.
• When your daughter brings home a new boyfriend to meet you your first thought is to check his backlinks.

Nice work Matt - we're definitely in need of something like this.
