When Grandma and Grandpa were visiting we shared a bottle of wine. No I did not let the animals have any. However we did clink our glasses together for a round of "cheers." Monkey saw us do this twice during their visit.
This weekend while we were watching the football playoffs Monkey took his sippy cup and went back and forth to us saying, "Cheers."
The co-zookeeper and I got a good laugh out of it, until Monkey nearly made me spill my beer all over Bear's head. That was the end of "Cheers."
