In the process, she has damaged the other presents, hence Cueball's wish that she had opened another present first.
The title text refers to two bacteria commonly used as controls to confirm that the technique has been correctly performed: Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative). Neither are bacteria you want to be coming into contact with in any substantial quantities, hence the need to stop accepting presents from "That Guy".
I would buy one for the people I know, but they apparently cost 140$ upwards. Randall is a rich man. Davidy22[talk] 08:23, 24 December 2012 (UTC)

Do E. coli bacteria mask the response of Staphylococcus? Do the responses go through the gift wrapping? The gift from the guy should have shown Gram-positive, because of Staphylococcus. Thus the mistake. --126.96.36.199 13:08, 25 December 2012 (UTC)
Of course, the dye used in Gram-staining is DYE and will color hands, clothing, (wrapping) paper, and floors. Megan might not have a bunch of bacteria coated presents (except for the one from That Guy in the title text), and instead she has just ruined her own Christmas.

- Given that she colored the wrappings, most presents should be still fine. Especially considering you usually wrap the present INCLUDING the original packaging. -- Hkmaly (talk) 09:27, 27 December 2012 (UTC)
I found this funny, especially with it seemingly be tangentially related to Depth-First Search (DFS). Genux (talk) 00:42, 26 December 2012 (UTC)
Most species of Staphylococcus (such as S. epidermidis) are harmless; most strains of E. coli (with the notable exception of O157) are harmless. --Prooffreader (talk) 09:13, 26 December 2012 (UTC)
Is it just me or does the one on the left on the third frame seems to be purple (Gram-positive)? 188.8.131.52 02:35, 2 January 2013 (UTC)
I just noticed that her hands are stained purple in the last frame. 184.108.40.206 16:12, 4 January 2013 (UTC)
- I don't know...they look pink to me.--Dangerkeith3000 (talk) 22:30, 7 January 2013 (UTC)
In mine they are pink (might be your monitor), and if you compare the second and third frame the striped present is not purple (Gram-positive) it is in fact pink as the rest (just dark due to the stripes on the wrapping paper). My question is why are her hands not stained purple in the second panel/frame... is she more careful with the first dye and not the second? Also, with "that Guy" referring to Santa are they implying that he pets his Reindeer and they have E-Coli on them like any other animal (lack of hands to try to wipe it away). ~~MIRAnger
Wait, why is 'That Guy' White Hat? Surely it should be Black Hat due to his habit of posting bobcats... 220.127.116.11 07:45, 31 March 2015 (UTC)

It also appears that Megan skipped the necessary decolorizing step (ethanol or acetone) that prevents the purple dye from obscuring the pink for Gram negative cells. Dumping the dyes onto presents would not require this step, but it would also not provide any insights into the "cell wall" of the presents. Also she missed an opportunity to do something ridiculous with intoxicants and/or solvents! Perhaps Megan didn't read the instructions carefully, in addition to whatever weirdness led her to dump dyes all over the wrapped presents.
