Didn't the bumper just recently play on Adult Swim something last week? (I forget if it was this week or last week when I saw it, I think it was last week.)

EDIT: I think it was on a Sunday (7/22) because the last few re-airings were on Sundays.
Yes, it's running this week. It pops up periodically... I wonder if there is any reason for this particular bump making repeat appearances. Or if they just want us to keep wondering "Wha'd I do now?"
I also caught a glimpse of the Home of the Napping Ponies (http://www.bumpworthy.com/bumps/4054) bump last night.
