Good one!

Some of my favorites for Mathematicians:

"Proof is trivial"

"It is clear that ..."

"It can be easily shown"

And here is one from a math text:

"I never came across one of Laplace's 'Thus it plainly appears' without feeling sure that I have hours of hard work before me to fill up the chasm and find out and show how it plainly appears".
