The last time I even heard Obama mention Bo, this was the reference:
Mr. Obama concluded his remarks at about 7:30, saying he couldn’t stay for dinner.
“I’ve got to go home to tuck in the girls and walk the dog and scoop the poop,” he said.
“As a matter of fact, I even got some Portuguese enrichment stuck on my shoe the other day.”
Update: Obama told the Portuguese that Bo is “the most popular member of the White House.” Hey, even a broken clock is correct twice a day.
