I'm putting that stamp as a business expense.

AKA what I've been doing the past three hours:

Assignment Question: Based on your data, what is your measured n(f) value for your most intense peak near 650 nm?

Hapless Student: HERPA DERP MY DATA OBVIOUSLY SAYS 5, BUT LITERATURE SAYS VALUE IS 2, SO I'LL JUST WRITE THAT

My response:

It's especially hilarious when they write the literature value, and then go on to talk about how they had obtained it from experimental data when it's entirely obvious that the procedure they describe would lead them to the EXACT OPPOSITE conclusion. Lololololol
