Two new clips have been released from The Big Bang Theory's season 8 double-bill premiere. The hit comedy returns to CBS next week, with Sheldon (Jim Parsons) returning to Pasadena after deciding to go travelling in the seventh season finale, reported Entertainment Weekly.
Watch:The Locomotion Interruption
In the first clip from The Locomotion Interruption, Sheldon tells girlfriend Amy (Mayim Bialik) that he wishes he had never gone on his trip, with Leonard (Johnny Galecki) revealing that his roommate had spent the summer travelling across the country via train.
Sheldon also notes that the adventure has strengthened his character, declaring himself 'Sheldon The White' in a nod to Ian McKellen's return as Gandalf The White in The Lord of the Rings trilogy.
Watch:The Junior Professor Solution
A clip from the second episode The Junior Professor Solution sees the group enjoying a discussion about theoretical inter-species relationships.
