Somebody say cheesey?
I used to use Journey's "Don't Stop Believin'" but it has since been co-opted by the Sopranos.
Depending on how old the person is, The Culture Club always gets a good laugh, anything by a Boy Band (NKOTB and 'N Sync bring the house down), and the aforementioned long hair power ballad from the late 80's early 90's.
