Do you blunderstand?

Alice in Sunderland
Malice I understand
Alice in Blunderland
All is in, understand?
Walrus tinned under sand.
Sallies by guns unmanned.
Call us in Thunder Band
Phone is in Alice’s hand
iPhone in political scams
Trellis blows down in wind.
Four letter words gave me wind.
Before litter, we all must be banned.
Bellicose man in grandstand
I wish I could do a handstand.
Where was that Alice he stunned?
Algebra made me a man
