"If i wanted to bake a huge amount of choc chip cookies, say, like, in the millions how many ovens would i need and how long would it take to bake those cookies..."

This obviously assumes they're a kosher jew.

Ask them what they're doing on Saturday, maybe see if they'll help you do some work. All depends on the situation though.

"My mother, she's jewish,....."
