I'd try breaking into a chorus of "Suppertime!" from Peanuts every time she mentions it.
Sorry, can't post a clicky link for some reason but . Song starts at 1:38.
Snoopy sings, while dancing around his bowl:
Suppertime!!
Yes, it's suppertime.
Ooh, it's sup-sup-suppertime,
Very best time of day.
Suppertime.
Yeah, it's supper time.
And when suppertime comes
Can supper be far away?
Bring on the soup dish,
Bring on the cup,
Bring on the bacon
And fill me up 'cause it's
Supper, supper, supper, supper, suppertime!!
Br-r-ing on the dog food,
Bring on the bone,
Bring on the barrel and
Roll me home 'cause it's
Supper, supper, supper, supper.
Super super-pepper-upper,
Supper, super-duper suppertime!!
Wintertime's nice with the ice and snow,
Summertime's nice with a place to go,
Bedtime, overtime, halftime too,
But they just can't hold a candle to my Suppertime!!
Oh, yeah!
Br-r-ing on the hamburger,
Bring on the bun
Pappy's little puppy loves everyone,
'Cause it's
Supper, supper, supper, supper,
Supper, super pepper-upper,
Supper, super-duper-dupper
Dupa dupa dipa dapa, dipa dapa dupa dapa TIME !!!!!!
