Chalkboard Gag:

I do not deserve a Mother's Day gift for being 'one badass mother'

Couch Gag:

Opening on an empty Simpsons couch, the scene widens out to reveal a mock up of the Simpson' living room is in the Smithsonian Museum.
Homer, Marge, Bart, Lisa & Maggie launch grappling hooks onto the roof of the museum.
It should be noted that Maggie's is actually her pacifier and Homer's missed and clunks him on the head.

Marge is seen cutting a circular hole in a window but after looking at Homer's waist line proceeds to cut a much larger hole.

After walking by displays such as Dorothy's Ruby Slippers & Fonzie's Jacket, which illicits a thumbs up from Homer and a yawn from Bart, they walk by the Hope Diamond which Marge looks longingly at, they walk through various rooms of the museum.

Before they enter the first room, they walk by a janitor's closet so they change clothes to disguise themselves as janitors.
They enter an Egyptian exhibit so they discard their janitor outfits to reveal they are clad in mummy wrappings.
Leaving the Egyptian room they enter a modern art exhibit wearing outfits that resemble Jackson Pollock's work. This works to their advantage since they stand undetected in front of a Jackson painting to hide from two passing security guards.

They arrive at the display that looks like their living room but before Homer can sit on the couch, Lisa stops him and using an aerosol can sprays the display for light beam motion sensors.
Bart notices there are gaps in the beams that just happen to fit each of their bodies so they slide through with ease and sit on the couch.

This episode's title is an adaptation of 'Edward Scissorhands', the 1990 Tim Burton fantasy movie starring Johnny Depp and Winona Ryder, Dianne Wiest & Anthony Michael Hall
