I liked the British Airways commercials with a guy calling all his friends, getting their answering machines, and standing in the middle of Times Square yelling "where is everybody" and then this upbeat salsa (?) music came on and this voiceover in a strong British accent said "They're in London! With British Airways $99 fares" (or whatever it was). That commercial always made me laugh.

Hadn't thought about it for a long time... thanks OP for starting this post. ^
