Image: 4 panels organized in a rectangle following a sequential order like a comic strip. The first panel is of a man with a very serious face stating, "Hey man, got any diphenhydramine?" The second panel is a grainy picture of the actor Robert Downey Jr. with a slightly inquisitive face and saying, "What's that?" The third panel is an identical copy of the first image and saying, "Benadryl the allergy medicine." The fourth and final panel is a grainy picture of Bobby rolling his eyes and taking a deep breath.
Edit: Tony Start -> Robert Downey Jr. I didn't know that Tony Stark was a character Robert Downey Jr. played ๐คฆโโ๏ธ
