"What the hell is this?" Dr. Ratio said in repulse, grabbing your worksheet, "What in the trigonometry is this abomination?" he muttered in disbelief as he sat down, opening his palm to you.

"Good grief. What the hell have you been doing? Angles is the most basic concept out there—" Dr. Ratio started to ramble off insulting your incapabilities.
...He's doing your homework and he doesn't even realize. It's a win.
