Stephen Colbert and Jimmy Fallon are Best Friends For Six Months (BFFSMs), so it's no surprise that they have been showing up on each others shows, having a couple laughs together. After Colbert auctioned off his portrait for Donor's Choose charity for $26,000, he announced that Fallon would be matching that amount with his own donation...without asking Fallon first.

Of course, he didn't ask Colbert first either.
