A skit of any kind and perform it with the 'Pythons', what would it be.

Mine would be as follows:

Return of the retarded


Me and Graham would be talking to each other but retardedly.
"Duh duh duh duh duh"
"Duh duh duh duh"
"Duuuuuuuur"

Then dramatic music would play and Eric would step out of no where and start singing the "Tard Song"

And then for something completly different.
