I’m dying!!! 
But Bob is getting way too much attention in this forum as it is.
The funniest ones I’ve seen are requesting, “roasts” of photos.
I sent this photo of bid day from our state flagship to a friend. No idea of the exact prompt he gave it to roast this photo, but this was what he got:
“Welp… guess I’m switching my major to whatever that is.”
“Careful if they all say ‘like’ at the same time, we’ll crack the Richter scale.”
“I didn’t know Barbie had a military.”
“One pumpkin spice latte in the center of that crowd and we’d have mass hysteria.”
“Imagine the line for the bathroom. Just imagine it.”
