Uncanny X-Men (1963-2011) #5

The X-men return to their headquarters with an injured Professor X. While chasing down the Brotherhood of Evil Mutants, Professor X was caught in an explosion that seems to have robbed him of his telepathy. The X-men put Professor X to bed. They are soon interrupted by the arrival of visitors. Jean's parents (John and Elaine) have come for a visit. The X-men scramble to get into normal attire.
