Just about everything....too many to list but here's some...

traffic cones, of course
fast food restaurants remind me of onion rings and MOFF
cows remind me of Gini (she's got a room in her home that's totally dedicated to cows)
lemons remind me of Laurie and Zippy and us making lemonaide
I see a stuffed monkey in a store and I think of Willie and Mario
coupons remind me of Kelly and Karen (Wolflady)...it's too long of a story to tell...
The other day I had to use my blender....well, a certain someone came to mind....

the list goes on and on...
