A lucky guess
What was the password?
Catch of the day
Magic hands
Her whole world's come undone
A stand up guy
Hunky - Dory
Been there, done that
And a smooth talker
Ah, ah, ah! You didnt say the magic word!
it's coarse, rough, irritating, and gets everywhere

Some things just get better
And make it double
It takes two to tango
Right tool for the right job
Finder's keepers
Breath of life
