IRONY!

AE and KA gave husband CB a t-shirt with the chemical sign of iron. He likes to wear it to his chemistry class (chem. for nursing students) on the night of the first test. That was last night at the local community college.

CB says that on the first test he always has a question about Fe/Iron. The students rarely get that question correct, even though the answer is on their professor's shirt! (And last night's exam was no exception.)

I think it's cute. Too bad CB's students don't notice.
