David Spade Obama ... Thirstiest Prez Ever

12/27/2015 1:00 AM PST BY TMZ STAFF

David Spade thinks President Obama and Michelle have gone over the deep end and are becoming downright embarrassing to the office.

David was leaving Craig's when he groused about the President appearing on a reality TV show, GQ and Michelle becoming a staple on "Ellen."

Listen carefully to what David's saying ... sounds like he thinks this is all a prelude to what we'll see when they leave office.
