Canadian comedian Seth Rogen has always been associated with weed - having starred in stoner films like Pineapple Express, Knocked Up, and This Is The End. Is he ready to sit on the thrones of Cheech Marin and Tommy Chong, the iconic pothead duo?

Just a few days ago, the 31-year old actor revealed to Andy Cohen who he have smoked weed with. Included in his list were Paul Rudd, Sarah Silverman, Jonah Hill, and Snoop Dogg. He also admitted that he and Barbra Streisand have talked about weed a lot, but they have not smoked together yet. Rogen said, "She smoked weed with Peter Sellers though. That's the craziest s*** ever!"

What surprised everyone was when Rogen admitted that he never smoked pot with Pineapple Express co-star James Franco. He even said, "He doesn't smoke weed. That's why he's such a good actor! It's really sad, actually."

So who else is on Seth Rogen's weed buddy list? During the actor's appearance on Capitol Hill, Arlette Saenz of ABC News asked him: "Is there one politician you'd want to smoke pot with?" The actor answered, "That Harkin guy seemed pretty cool. I'd go with him."

Based on the report of Des Moines Register, Seth Rogen and U.S. Senator Tom Harkin shared a few laughs during the actor's testimony before the Senate Appropriations Committee. The Register asked Harkin's office if the senator will be interested in smoking marijuana with Rogen. Harkin's spokeswoman initially replied, "No comment." But she later on said, "Ask us again in January 2015."

For those who don't know, Senator Tom Harkin will be retiring this year so that means he will have more time to do anything he wants. Maybe we will spot Seth Rogen having a weed session with the senator in Colorado soon. Who else do you want to see become Rogen's new stoner buddy?
