I don't think they say this anymore, but I remember something to the extent of, "please collect your belongings and take small children by the hand..." as you were exiting some of the rides. I say this all the time when we are getting out of the car, or trying to gather our things when leaving a restaurant, etc. DH just rolls his eyes, but the kids still laugh when I say it!
Also, DH usually butchers the names of things, so we have lots of funny names that have now become "normal" for us:
Cosmic Rays = Comic Rays
Pecos Bills = Peso Bill
Ghiradelli = Geraldi's (hard "g" sound, like "good")
Ohana = Moohanie's (moo-HA-nees)
The last one is our absolute favorite and can send us into fits of giggles when we talk about going to "Moohanie's" for dinner!! I have no idea how he comes up with this stuff, but it keeps us in stitches!
