I interviewed Gallagher for a newspaper I worked at in Massachusetts back in 2003. It was one of the best days of work I ever had.
A few of my friends and I have been obsessed w/ Gallagher forever -- probably from the night we were intoxicated and watched one of his specials where he's rollerskating while being towed by a car and then trips and nearly rips his arm off. He has this insane thing called "40 Doors" which is this business plan he has to have a hotel w/ 40 doors which is somehow ideal for family reunions that we also saw him talk about somewhere that was so brilliant in its inanity and delusions.
Usually when you have to interview a somewhat famous person it's like this 500 step process. For Gallagher, I found his agent's contact on a Geocities page. He gave me Gallagher's number and told me to call him whenever. When I did Gallagher picked up literally after half a ring.
I naturally began my interview with him by asking: "Gallagher, is it okay to refer to you as a genius?"
I was then on the phone w/ Gallagher for about an hour. It was completely insane and one of the best things ever.
