On Thursday's "Imus in the Morning," Don Imus and Chris Wallace joked about Sarah Palin sitting on Wallace's lap when she appears on "FOX News Sunday" this weekend.
"When you interview her, will she be sitting on your lap?" Imus asked.
"One can only hope," Wallace replied.
Wallace had previously compared Palin to a whale he's been chasing for over a year.
"We've been chasing her like Captain Ahab and the Great White Whale for the last year-and-a-half," he said.
Palin will appear on Wallace's show from the Tea Party Convention in Nashville.
