Louis C.K. Louis C.K.

It's been a good week for Louis C.K.  In just two days, the comedian raked in a whopping $4.5 million by selling 100,000 tickets for his upcoming comedy tour.

"Well. after 45 hours, my tour has sold 100K tickets, box office gross of 4.5 mil $ (not all mine)," he tweeted on Thursday. I guess it was a good idea."

The comedian began selling tickets via his website on Monday. He opted against using mainstream ticketing vendors like Ticketmaster in order to keep his fans from paying processing fees. Tickets immediately sold out, prompting C.K. to add more show dates and venues.

C.K. has made a bit of a splash by cutting out the middle man. Last year, he offered one his latest stand-up comedy special to fans as a $5 download rather than sell it to a TV network. He made more than $1 million in 12 days, much of which he gave to charity.
