Mal and Chad's Fill in the Bubble Frenzy 19

It's time once again for the Fill in the Bubble Frenzy with boy genius Mal and his talking dog Chad! Tell us what goes in the empty speech bubble and you might win any T-shirt available in the NeatoShop -take a look around, pick one out and tell us what shirt you’d like with your submission in the comments. If you don't specify a t-shirt with your entry, you forfeit the prize. Enter as many times as you like (text only, please), but leave only one entry per comment. For inspiration, check out Mal and Chad’s comic strip adventures by Stephen McCranie at malandchad.com. Good luck!

Update: amanderpanderer's line was selected to go in the speech bubble: "We always did make quite the paramecium." She'll be getting a t-shirt from the NeatoShop!
