'Super-Cala-Fraggalistic-Expee-Ally-Doscious' ?
OR: If you really wanna catch a Rept'y on the hop...
'Peter Piper Picked a Peck Of Pickled Pepper, a Peck Of Pickled Pepper Peter Piper Picked' ?
OR: If they catch you in a dark alley at night challenge them with this and you will have em stumped on the spot...
'Chimm-Chimmeny-Chim-Chimmeny, Chimm-Chimm Charoo'!
