You know you spend too much (Time/$/?) on Festool or the FOG when...
When you play hookie from work to attend the Festool demo day at your local dealer.
When your web browser home page is your Festool dealer.
When you decide you can drive your 15 year old vehicle another few years so you can afford additional Festool tools.
When you can't sleep at night because you're trying to figure out how you can re-design your workshop to accommodate more Systainers.
When the only time you've ever lied to your wife in 23 years of marriage is when she asked how much those tools cost and now you have to hide the Festool catalog like a teen-age boy hides pornographic magazines.
and, you know you're really stone cold drunk on the green Kool-Aid when your wife is "in the mood", but all you can think about is reading the new Festool catalog that just came in the mail...
