On 'The Colbert Report' (weeknights, 11:30PM ET on Comedy Central), Colbert announces that Comedy Central will donate money to cleaning up the Gulf of Mexico oil spill each time someone re-tweets a specific tweet by him.

After making the announcement, Colbert then tweets the following: "In honor of oil-soaked birds, 'tweets' are now 'gurgles.'"
