Celebrate high times - come on!
We're guessing Rihanna is enjoying her Labor Day weekend if these videos are any indication!

We previously posted a video of Stephen Colbert's newest ad, asking the people of South Carolina to vote for Herman Cain.
The ballot has been locked, so Hermain Cain's name is on the ballot, even though he's no longer running, and that also means Colbert can't get his name on the ballot.
Other than making the ad, Colbert took it even further by actually going to the campus of the College of Charleston and held a rally in front of 3,000 students.
Check out his HIGHlarious speech in the above vid, as well as his ad, incase you missed it.
