Mike Huckabee is still battling for the Republican nomination despite long odds, but said Saturday he won’t “overstay his welcome.”

Then he did precisely that on Saturday Night Live.

The former Arkansas governor appeared on “Weekend Update” and expressed confusion over whether it’s mathematically impossible for him to win the nomination over current front-runner John McCain.

After anchor Seth Meyers explained the numbers, and that superdelegates only vote in the Democratic primary, Huckabee deadpanned: “Uh-oh.”

However, he said: “Mike Huckabee does not overstay his welcome. When it’s time for me to go, I’ll know. And I’ll exit out with class and grace.”

Huckabee then remained seated at the “Weekend Update” desk long after Meyers made it clear it was time for him to leave.
