This cartoon by Matt from The Daily Telegraph relates to news that CERN scientists reporting from the Large Hadron Collider (LHC) have claimed the discovery of a new particle consistent with the Higgs boson. The particle has been the subject of a 45-year hunt to explain how matter attains its mass.
The joke is that the scientist has not lost his glasses at all—they are on his head. The cartoonist plays on the stereotype of the 'absent-minded professor'.
Note the irregular past participles: lost (lose, lost, lost), and found (find, found, found).
