Yup - I've got one of these t-shirts as well. 3 other partners, 2 of which contributed nothing at best. (One of them was trying to double-dip by acting as a reseller of our services with a 3rd party - wonder why THAT didn't work out well?) Additionally, even though one of the partners did nothing but sales - I closed every single deal we ever got. Which is what I was hoping to avoid by giving away 20% of the revenue to a sales person :)
Not sad that we gave it a go - but disappointed in the results as it definitely could have paid the bills for a few years...
