Take over the job of the Biblical "flaming Bush"

My wife's parents would make a Ideal pair to take over from Bush_Rice.

My wife's farther ( may he soon be with his maker ) has a space ship... he regularly rockets off to Mars where he contends the water is the absolute best, he also slips away to Venus, but finds the winds and the smell unbearable... so proving he has a lot more knowledge of out of world experiences than Bush.... his wife sits there nodding knowledgeably, whilst knitting endless scarves with a adoring look on her face.. and she loves rice.
Unfortunately she is a little wary of him as he intends to sell the nursing home they live in and move it to Mars. They both have Alzheimer....... What's Bushes excuse.
