Blue Jellyfish???

O: Jessica, what's that big blue jellyfish for?
Me: Huh??
O: That blue jellyfish
Me: What blue Jellyfish?
O: That blue jellyfish right in front of you

Me: (after a few seconds of trying to figure out what the heck she was talking about) Oh, that's not a jellyfish, that's a bright light.  See, watch the road when I turn it off and on.
Tyler: Yeah, but if you turn it upside up, its a jellyfish
Me: Oh yeah, you're right! (smiling inside)
