It’s shoo-in, not shoe-in – “Shoo-in ‘easy winner (especially in politics)’ (1939) was originally a horse that wins a race by pre-arrangement (1928; the verb phrase shoo in in this sense is from 1908).”
Fred Flintstone is an assumed name – The name “Flagstone” isn’t the only difference you’ll see in this 90 second demo reel from 1960.
In the jungle, bet on the jaguar, not the crocodile – OK, technically this is a caiman rather than a croc, but you’ll see what I mean. (By the way, one animal meets its demise in this National Geographic video. It’s from a distance and not graphic, but fair warning.)
I bet this blog post is a shoo-in for most edifying and illuminating of the day.
